i just received my t60 yesterday
after 2 and half years using T40 ..

T40 gave me zero problems at all ...
almost i can say average i turn it on for min 6 hours everyday for the past 30 months but still, no problem ..

superb machine ..
i hope my new t60 can serve me better.

btw ..how much 2nd-hand price for t40 docking system and extended battery.
