It was a real mistake not to make studio5 a cross platform IDE.
Atmel needs to support Win/Lin/Mac
I still mostly use studio4.
But the AVRStudioX debugging with the Dragon is an incredibly sweet deal. Long ago and far away I designed a hardware emulator for the Z-80 and Z-8000 at a cost of roughly a zillion dollars. That didn't have anything on what is available today for free. Yea progress!
