I have a droid 1 that is about 10 months old now and about a week ago the touch screen suddenly seemed to lose sensitivity. I have to tap on the same button numerous times before it registers a touch quite often now. It's as if the sensitivity used to be 100% and it suddenly dropped to 40%. It's especially aggravating when trying to use the soft keyboard. It is stock 2.2 and removing the screen protector made no improvement. Does this sound like a warranty issue? It's not quite a year old yet.
