Found this on Neowin:
Apple has initiated a worldwide battery exchange program for certain rechargeable batteries that were sold for use with 15-inch MacBook Pro computer systems from February 2006 through May 2006.
We recently discovered that some 15-inch MacBook Pro batteries supplied to Apple do not meet our high standards for battery performance. To give our users the best experience possible, we will replace these batteries for customers free of charge.
…
The affected batteries have model number A1175 and a 12-digit serial number that ends with U7SA, U7SB or U7SC.
Mine was one of those affected. I was thinking the battery life was a little weak — glad they realized it too!

So, I decided to try to do an upgrade on my home PC to the new Vista build 5472 (preview). Previously, this machine was running Windows XP Professional. It's been a while since I've taken a look at Vista…probably Beta 1. With 5472 being the post-Beta 2 build, much has improved. The upgrade process was very slow, but I am pretty impressed that everything seems to be functioning normally. I usually hate doing upgrades, and I really don't have anything important on that machine, but I thought I'd try it anyway. A lot of things have improved greatly, but it still appears to be slow. The first day was unbearable — I know it was doing some indexing and defragmentation, but the hard drive was running like crazy. Anyway, I really wanted to see the new eye candy and the PC I have at home didn't have the capability to do Windows Vista Aero. It has an internal video card…but, I soon fixed that problem. It was a good excuse to go get a decent video card, and I picked up a basic ATI Radeon X1300. Wow – I really like the 3D window animations. Needless to say, I'm very excited about Vista. I'm also very excited to see what Apple has in store for Mac OS X 10.5 Leopard (it'll be demoed at the Worldwide Developers Conference on August 7). A co-worker was showing me Xgl on Linux too, which looks really slick too. I think that's definitely the future of desktop computing. It has the potential to help with organization, and it's definitely fun to play with.
