I recently purchased the Macbook Pro 15 Inch at the Applestore. The buying experience was very good. If you are employed by a large company or the Government make sure you inquire about a discount. Also remember that Students and Teacher get a discount as well. These discounts can range from 6 to 8 percent.
The technical specs of the laptop are impressive. The performance is extremely snappy, but it is hard to see a difference between it and my old Macbook. However the screen is noticeably brighter and richer than any laptop I've ever looked at. Now every laptop looks like I'm looking at it through a layer of dust.
I have noticed that at low screen brightness there is a very annoying flicker visible. My understanding is that due to the nature of LED back lights to get a dim light they are cycling the LED's on and off very fast. Some people can see the flicker. I'm one of them.
Carrying the Laptop is a joy compared to anything else I've every picked up in this screen size. It is sturdy and light. I really don't notice a difference in weight between it and the old white Macbook.
PROS: Light weight, beautiful screen, Sturdy construction, lighted keyboard, processing power to spare.
CONS: Expensive, screen flicker at low brightness.
Nutshell: If you can afford it, this is a great laptop.

Mac OS X Your network has been compromised revisted
To see a description of the problem check out this old post.
Mac OS X Your network has been compromised
It appears one of the latest updates to Mac OS X has fixed this problem. I can now have my MacBook remember networks that have multiple access points under the same SSID.
I think the specific update that corrected the problem can be found here AirPort Extreme Update 2008-004
This has been a problem since around the First of 2008. Little bit slow on the old repair.

Drobo + Droboshare
This is my new Drobo sitting on my poor mans computer rack in my office. I've had it about two weeks now.
This is the older USB 2.0 only model. When the new model with Firewire was introduced this model had a price cut. I was all ready to buy it off the Drobo site with a promo code when I realized that once that added shipping on I could still get it cheaper from Amazon. I also purchased the Droboshare attachment to turn it into a NAS (Network Attached Storage) device. I ordered two 750 Gig drives from Newegg to complete the set. Newegg has consistently had the lowest prices for drives. I've since added a 640 Gig drive to give me a bit of boost in redundancy. I've also added a Dlink Gigabit Network switch to try and improve transfer rates. The one computer I have with a Gigabit card in it only saw modest speed increases.
All my experiences have been with the Drobo in conjunction with a Droboshare so keep that in mind. Expansion of the device is really the hallmark of it's simplicity you just add an additional SATA drive and you increase your redundancy protection and over all disk space. With two 750 Gig drives and one 640 Gig drive I have access to 1.26 Terabytes of redundant data storage connected to my home network. Any one drive can fail and I will have no data loss. This is a comfort since if I have a single drive failure in my Linux server the whole data volume is gone.
One important item with the SATA drives you place in it. Make sure the are set to work at high transfer rates. You might have to fiddle with jumpers to turn this on. SATA drives come in 1.5 and 3.0 Gigabyte transfer rates. Some of the 3.0 Gigabyte SATA II drives are configured to run at 1.5. So make sure you are getting your moneys worth and get the jumpers right. Honestly I did not see a difference in transfer rates but I feel better now.
My purpose for this device was to provide redundant storage from my digital pictures. A 10 Megapixel camera can eat up storage fast. And a place to protect all my music library. I have started using the Drobo as the primary storage device for the pictures but just a backup up for the music. I want to keep the music on the Linux server for now as the primary source.
Transferring vast amounts of data over the network takes time. My transfer rates are much slower than I would have expected I'm not sure if this is because they are coming off a volume group in Linux of if I have an issue with my network. The data is moving at 10 Megabit speeds even though I'm on a 100 Megabit line for the Linux server. The iMac is transferring at acceptable speeds but it is on Gigabit and should be faster. Maybe the USB 2.0 connection to the droboshare is issue.
Pros: Setup is easy, expansion if totally easy. Footprint is small and you don't have to worry about configuring a RAID array on your computer. Your data is protected from hard drive failures. You get a lot of usable storage considering it is also providing redundancy. The set up was fairly easy but some of that will make it into the cons. The tool to manage the device is pretty straight forward and effective. To your computers it shows up as a standard SMB (Windows) file share pretty easy to access. I have a mixed environment to so my Mac's, Linux Boxes, and Windows machines can all see it, use it, and share files. Double plus good.
Cons: You still have to understand about drive formatting to get it up and going but you can get a geeky guy or girl to help if needed. You should just plug it into the network and the client tool supplied with the Droboshare is supposed to find it. I had to plug and unplug and reset and fiddle a while before it finally came up. I have the same problem if I place it in standby mode it really does not want to come back to life. I've had one power outage where it can back fine I had an accidentally unplug where I thought I would have to send it back but it finally woke up and the client was able to see it. That has been the biggest issue I've had with it. Also the Drobo client install keeps wanting to make it load on startup I don't want it to and have to convince it of that every update. Oh yeah it really is an expensive solution.
Needs to have: The Droboshare really really needs to support some type of rsync capability. It based on Linux and they just released an SDK someone really really needs to compile rsync for it. This would make transferring files to it so much easier. My 100+ Gig music library takes over 26 hours to transfer. This is due to the slow transfer speeds off the Linux server but rsync would really fix that.
Nutshell: If you have digital bits of data that you want to share and protect this is the device to buy. It excels at simplicity (when compared to other solutions). Allows you to maintain control of your media. If you are buying music, movies are taking hard to replace photos go buy one today. With today's hard drives it is not if you will have a failure it is when. Remember though it is just an onsite backup if your house burns so does your data, to be truly secure you will also need some sort of off site backup. Like Jungle Disk or Mozy.

Computers are hard
I've been working with computers since the Apple IIe. I've owned more than I will take the time to count up. My circle of friends all have some bit of computer literacy and yet day after day I'm amazed at just how hard it is for people to use computers.
In the days before the Internet people could get a computer take it home put their check book in an application keep track of lists and print out letters. The computers all did that pretty well. There were problems getting the printers hooked up sometimes and you would have to buy an application or two for the balancing of your check book and the keeping of that list or two. Computers were expensive and not that many people had them. Software was expensive too.
Today a computer is a much more versatile tool. It is a digital dark room, a high tech video phone, a music studio, an entertainment center. They cost a fraction of the old one's their power is astronomic compared to what we had in the 80's or the 90's and we are connected to the world.
And there in lies a large part of the problem. We have to get them connected to the world. This entails cable modems, dsl modems, home routers, home switches, wireless access points, wireless cards, network cards, firewalls. Then all this has to be configured to work together and allow communication in certain directions and block communications in other directions. This has happened to me over and over someone says hey this does not work. Heck I've said hey this does not work. And realized hey that can't talk to that, I wonder why? Duh somehow a firewall got turned on. This happens over and over again. And I understand networking. To most people it is something akin to brain surgery or maybe rocket science.
Here is another common occurrence. A hard drive eats a file (consider this hard drives now rely on error correction to read files back) maybe it is a little file may seem unimportant, but too Windows it is one of those critical files required to get going. And there you have an expensive door stop that goes into a blues screen that isn't even animated or it reboots over and over again. If it is under warranty the maker might give you a new drive. But you will have to surrender your old drive and you will probably be told there is no way to get those 10,000 family photos off of there.
How do you keep that stuff safe then. Well there is external hard drive's I've had a friend that has had three of them fail and I think I have had one fail and another is acting strange. There is the Drobo. Wonderful bit of tech I will be writing about later. It is easier than some things to use and offers data redundancy. Here it is in a nut shell if you have digital items that are important get a Drobo and figure out how to store those important digital bits over on it. But then if your house burns down it is not going to be much help.
What about apple one might ask. Well Apple makes a very nice, powerful computer it has a lot of great features and they have done some very smart things. But honestly it is really not that much easier to use than a Windows machine. Sure there are some things that it does to help you out but it is still a mystery to a lot of people. But a geek moment here Unix is cool and OS X is based on Unix. So therefor it is cool.
So how did we get here and where do we go. Computers have a lineage that goes back to when they were used by very geeky people that understood the inner workings of them and they based there development on that understanding. Knowing the end users had the same understanding. Today it is hard for people that have an in depth understanding of how computers work to design things in such a way as to make sense to those people that don't live bits, bytes, or and xor's . Sure we have trained people to use them a certain way and like Pavlov's Dog people have come to expect a certain result from a certain action. If that doesn't work then turn it off and on again.
However computers are still very hard to use, set up and get connected. These things are all done in a way that is not very geared for common people. The terminology while correct means nothing to people outside of the discipline.
Maybe some day we will have devices that can self configure and can be worked with in a more natural way where the interface will make sense with out training. My hope is it won't be through voice commands though. If you think your office is annoying now with just the clicky click of keyboards wait till everyone is trying to talk their computer into doing what they want. Yeah, especially that guy that sits two aisles over is hard of hearing and rattles the windows when he talks on the phone. Yeah that is going to be fun............

Laptop Quality
I was reading this post When buying a laptop, make sure to look for build quality at the digital kitty blog. She talks about how great the Apple laptops are in form and function even though she is not crazy about the GUI.
If you have been reading here you might realize that I've personally had a very different experience with the build quality on my Consumer grade Macbook. My iBook was a bit better but something flipped out in it's logical board rendering it unusable so maybe it is not as good as I thought it was.
This has brought me to the conclusion most Consumer grade laptops are really junk. Even though we are paying upwards of $800 to $1200 for them they really do not hold up very well. Cracking cases, dead pixels, failed hard drives, memory failures, logic board failure, driver issues, etc. I have come to the point where for laptops the extended warranties are a requirement. Pushing up the cost another $200 or more. Extended warranties are generally a rip off for the consumer though.
My experience on Business model laptops is a bit limited, being mainly Dells. But then again they have not been the most robust. There were the C series latitudes that continued to break the latches. The other C series I bought off of e-bay with the keyboard that continually repeats characters. The C Series at work with the failed sound card on the logic board.
As I write this the conclusion I reach, is that modern laptops (since 2000) are just not built very well at all, Consumer and Business. They are just not made to stand up to the stress of being dropped in a bag and carted around every where.
Given the widespread use of laptops in today's world manufactures need to do one of two things price them as truly disposable items that are meant to last for a for a year or two and be trashed. That is a pretty stupid plan given how they need to be disposed of. Or match the build quality to the price and the consumers need, make sure they last about five years and can handle being carted around everywhere.
