Well I pulled the trigger tonight. I ordered an EVK1104 dev board. It's pricy but will give me alot more growth.
Alot more memory and program space.
Plus as an added bonus - High-Speed USB 480mb/s !! Can you say fast cd rom emulation!
The graphic display is an added bonus.
SD memory card - maybe I could do something with that.
CE-ATA interface - interesting, That would use alot less data lines than the HDD IDE interface.
I'll post info once I get this board and do some testing. It will take a little while to get fully operational. Code porting from the 8 bit will take some work, i'll have to check out Dean's site and see if LUFA is ported to avr32 - I though I cought somewhere where someone was working on it.
