I had the same GE Profile microwave for 15+ years and loved it.  The bottom started peeling which is the only reason I had to get a new one.  Aesthetically, this new microwave looks good and does a good job cooking, etc.  My one pause is the opening (not sure of the name) button.  It is horrific.  I'm hoping it will loosen over time.  If not, this may have to be returned.
