Super happy with the Nexus One... just minor issue is that on occasion - and not sure what triggers it - but the touch location seems to end being below where i actually touch on the screen, which of course causes erratic typing and erroneous screen clicks. A quick cycle of the sleep/power button (not turning unit off, just sleep/blank and back on...) seems to solve the problem.
Hopefully an update will resolve this issue, as it seems to be a software issue.
Same for me. Occasionally the screen freaks out and I turn it off (standby) wipe my hand accross the screen and back on. That always works. I wonder if it is a grounding or static issue. I have the latest stock version.
