um, we've had a lot of trouble with XO-1 touchpads, which is what mikus was using. i think this is the first report of serious erratic operation on an XO-1.5.
Sorry, you misinterpreted me. My experience has been with several XO-1s, NOT with the XO-1.5 -- that's what I meant when I said "the old keypad" -- I was talking about the one with three surfaces, not the one ("new") with only one surface. As far as I know, people have not been putting XO-1.5 motherboards into cases having keypads with 3 surfaces.
The one time I was using (touch-pad *only*, not mouse) both an XO-1 and an XO-1.5 in the same environment, the touch pad on the XO-1.5 behaved as I would expect, whereas the touch pad on the XO-1 was "touchy".

p.s. I attribute it to Alzheimer's -- but while I have a clear idea in my mind of what I am talking about, I see that that idea does not always get clearly conveyed to others. Right now, it is too much effort to keep straight when/if to say "touch pad" and when/if to say "keypad". [And no, please don't tell me -- I'll immediately forget anyways.]
