Query: Beware of m515 problems before you get one

I have owned it for about 5 months. it worked perfectly. All of a sudden the 515 stopped recognizing the connection to the PC and it used to freeze. Some times it just has the green light on and the screen is dead. palm is not addressing the issues pertaining to this nature of problems the right way. Hard or soft resets of the 515 provided no relief. SUDS and GLC are two issues to look for.I paid ($$$) and it was a waste. I'd advise prospective buyers to make a wise choice by reading about the problems on the web before one plunges for the purchase.
