The Mega is a chip I have been waiting for from Atmel for about a year (I
have had sample for a couple of months)..
Its fast, has In system programming, JTAG and a huge chunk of memory...
For me, its pretty much an ideal embedded CPU..

The ARM stuff is a tottally different ballgame ( I have an Atmel EB63)...
32Bit for a start, something like 4M of address space though there is no
discinttion bewteen code and data address bus's (non harvard architecure)...
The ARM is a REAL number cruncher... if you need to do a lot of BIG maths
quickly this is the chip for you..
Thoguh watch out, the ARM SDK is 1000UKP (and thats the lite version!)
also the chips are expensive..

The ARM and Mega are two different processors for two different types of
applications..
