The ibm thinkpad 600x is a truly great machine. Even in 2009, the thinkpad still preforms well with its maxium 512mb ram. I can internet browse, instant message, and listen to a cd all at the same time. The 500mhz processor keeps up with most applications. The build quality is great, and it feels like new even after 10 years. I also own a dell that is a few years newer, but it feels flimsy and cheap compared to this. The small size is good for slipping in a backpack, but the screen is still big enough that you never have to squint. Windows xp runs well on this machine. They go for fairly cheap on e-bay, so it's a great alternative to the many tiny notebooks that they are coming out with. They sell for around 150, which is less than half of what you might pay for one of those. Check it out, you'll be impressed.

This battery performs as expected for a new battery with my Thinkpad 600X battery according to both the computer's diagnostic and maintenance software and to my actual experience. Those that have problems with new batteries should run the battery rundown program or follow IBM's instructions for their computer. Rechargeable batteries in general perform best when used regularly and new batteries could show sluggishness from sitting in stock.
