I've had an M3 Lite, and currently an M3 Simply. I've been watching the release of the M3 Real and am considering purchasing one to replace my Simply. However, the Simply is working 100% perfectly for me. The Real looks interesting for the SDHC support and real time saving, which seem to be the only real additions, but I have read a few complaints of games not working 100%, or freezing during saving, etc. Is it worth the upgrade from the Simply to the Real?
