Pros: Great keyboard, screen, mouse
Cons: problems with my particular machine
I've owned many many Thinkpads, and still love them. However, my new R52 arrived DOA! The power came on, the "thinkpad" screen came up, then nothing. Tech support tried to help, but eventally took the maching back for repairs. When It came back, it booted fine, THEN it would lock the keyboard/mouse after a few minutes. Again, no rememdy over the phone, and it went back to IBM.
Finally got the machine back, and after 3 weeks of shipping if around, seems great. They keyboard/mouse pointer continue to be the best in the business, and the screen and overall look/feel of the machine is great.
