and I love it. ThinkPads are undeniably objects of desire, and people who use them tend to become attached to them - I've now had three.
My current machine is the X60 with a core duo processor. I beefed up the RAM, and it just flies along. It weighs 3.5 lbs, and is the computer that travels with me. The only slight drawback is the lack of a CD drive, but I have an external model I can use if I need to.
Otherwise it's a little dream of a machine.
