What I found a little puzzling is that some of the reviews I read
(sorry, didn't keep the URLs)
said that the battery times on the T60 (and X60)
were extraordinarily long -
one mentioned 11 hours, though when one read down the review
this seemed to shrink to 9 hours.
I don't see why dual-core should use less juice?
