I have a Thinkpad X41 Tablet that I really like. It was part of the very last product cycle to be branded IBM. Lots of people say that quality has gone downhill since then.
I owned a T42 and now a T61p. Even tough the build quality hasn't improved speaking of it having gone downhill is drastically exaggerated. The quality is comparable between the two, the nice little ideas still exist (like the keyboard light etc.) the only real change I saw was that i had to loosen 4 screws to extend the memory instead of four :-)
But one person probably isn't truly a reference... So more references are needed.
