I have an IBM T40.. great laptop.
If you're looking for a hardcore gaming laptop, this isn't what you're looking for..
But this is what it has..
lightweight, thin, looooooong battery life, IBM name/quality, excellent build quality.. among other stuff.. but those are the highlights.
You can still play games on it, don't get me wrong.. but don't expect to play the newest and latest games with four billion fps.
