Just the other day I had a half-dozen keys stop working altogether.

 

hmmm... mine seems to be in the same condition as the day i got it back in november

 

My D-Pad is crap now. I got mine the day after launch. And just the other day the top button to put the screen to sleep kinda jammed itself. Now you have to press a little harder to get it to work.

 

I had experienced some problems with my space key a month or so ago. I had had the phone since December, and ritually use the keyboard. It got to the point where I could barely put a space in, or when it did it would double space. I eventually called Verizon for a replacement under the manufacturer's warranty.
