Thanks!
Several of my exec staff have X31s. One has an X40 (yeah, I know we standardized on T41's but RHIP when it comes to SVPs

).
The exec who has the X40 moans about short battery life. He bought the larger extended battery and now it's almost as heavy as the X31. He wishes he got the X31.
Anecdotal evidence, I know.
When I looked at th etwo side by side, the X40 didn't impress me as being all that much smaller or lighter than the X31 (though it is both).
Unless you absolutely have to have the tiniest (then IBM probably isn't your best bet anyway), I'd recommend the X31.
