This is certainly not the final word on the question, but I have found that regularly cleaning (at least once a day) the touchscreen prevented the problem from happening and that a microfiber glass cleaning cloth was very effective.

If it's a known problem with no fix then i will live with it, try cleaning the screen more often etc.
However, if HTC has a fix i'll like an exchange because it is quite annoying sometimes. Just don't want to bother sending it back and being without a phone for 2 weeks if all they will do is send me a re-conditioned replacement.
I've had the issue like once in the last 6 months. I'm surprised to see it's related to cleanliness.. although I must say I keep it relatively clean, apart from the usual smudges.
I thought it was more related to something electrical.. seeing as the problem used to occur more when it was plugged in. But for some reason it just stopped happening to me.
Too bad like 90% of the Nexus' flaws are caused by the crappy Clearpad2000 digitizer.
Apart from that it's just one big chunk of awesome.
Your issues are stemming from the Clearpad 2000 digitizer. It is horrendous at keeping track of any multi-touch. Since the issue is hardware base and google has moved on to the Nexus S I wouldn't expect any sort of update to fix it, it's something we have to live with.
Honestly the easiest thing to do when this happens I've found is to just hit the power key up top to blank the screen and then hit it again to bring the screen back up. Gets rid of the calibration issue immediately.
Not too much of a hassle, only happens once in a blue anymore.
I've found that I start getting digitizer issues at around 300 - 350 hours of up time. Since I installed 2.3.3 I haven't run continuously that long yet. A reboot always cleared up the problem for another few hundred hours. Lately I've been rebooting at least once a week to keep ahead of the issue. Not that big a deal for me, but perhaps my particular N1 isn't as bad as others.
Everyone is so quick to show how knowledgeable they are about multitouch issues that they didn't bother to ever read the post to see that's not the problem being discussed at all
The calibration problem that shows up, particularly when plugged in, is a software issue, as demonstrable be doing a sleep/wake cycle, which makes it go away temporarily.
Since getting the GB update, it has not happened at all, so it seems to be cured.
I continue to have touch screen issues with my N1 when it is plugged into the car dock. A quick turn off / back on resolves it, but it is quite annoying. I thought it was decided long ago that it was an issue with the hardware behind the touch screen - no?
At any rate, Gingerbread didn't fix / improve the issues I've been experiencing.
Long before the Nexus One launched, the media was filled with speculation, buzz, rumors, and excitement regarding the possibility of a "Google Phone". The rumors were put to rest when Google announced the Nexus One, the first ever Google ... Read More
