Go to AVR, do not look back.  I finally did.  An undocumented bug in 
usart hardware that made code fully working on two chips fail weirdly 
was the last straw.  Fortunately since I knew the code was fine I only 
lost a day and a half - had I been doing the original development with 
this chip, it would have been a week gone.  Microchip is run by the 
marketing/sales dept. not engineering.  I've been pretty impressed by 
AVR studio + winavr (GCC port) though it has only been 3 projects so 
far.  Really - leave mchip behind.
