Lenovo ThinkPad Z61m

Even the wireless worked well on my Z61M. The screen resolution on the Z61 is much better than any of the T60/T61 systems that I have come across (equivalent to the T60P/T61P but has ATI graphics rather than NVIDIA). If they weren't getting long in the tooth now and harder to come by I would recommend the Z61 as a good machine for eCS.
