I work for a company that has always bought IBM computers. I have had three computers in my 10 years there. 2 laptops and one desktop. I have had this laptop (IMB T60 Thinkpad) for 2 years and have had a number of issues with it. I have received the "blue screen of death" and on boot up sometimes it would freeze. These issues only increased when I decided to add an extra 1 Gig of memory. Also after adding the memory the screen would freeze in the middle of working. The 1 Gig of memory was not the cheapest either. I bought name-brand Kingston memory. Due to the freeze-ups I have lost a lot of work. I have since removed the memory and the freeze-ups have stopped but not the occasional blue screen and boot up freeze.
Another issues is related to the docking station. Sometimes the laptop does not undock properly and takes a while to recover after undock/dock. I have also had the occasional wireless network issues when docking/undocking.
Other than the problems, this computer has some decent features. I like the screen. I run at 1400x1050 and it looks good. Speed is so-so, it was definitly an upgrade from my previous laptop (IBM T40 Thinkpad). My T60 has a Intel Core 2 T5600 @ 1.83GHz. DVD works well.
Others in my company have also had issue with these laptops. Many have complained about network and screen resolution issues when docking/undocking. I would recommend staying away from the IBM T60 Laptops in general. I think the quality issues have increased since they moved to lenovo, because I do not remember this many issues with my IBM T40. I have not had the chance to try the newer laptops, so I hope IBM has made improvements.
