i.e. compared to the original NES...that was 8 bit, correct? How many bits
is GBA? What console does it compare to as far as bits/technology go?

32 bits, technically. Although it compares better to an SNES (which is
sweet if you loved the 16 bit generation). Most of the games for it are
like SNES games. Some are quite a bit better.

(Specs follow)

After everything is crunched, from a user standpoint, I'd probably compare a
GBA with a SNES.
