This is the type of stuff I want to hear (I'm replacing my 4 year old laptop in the next two months)... what's so good about thinkpad keyboards?
It's a bit hard to explain, the travel on the keys is just really good, comfortable size and shape, etc. See if you can borrow one for a day and type on it, it took me an hour or so to get used to but now any other laptop keyboard feels wrong.
