The Micro is tempting, but I’d almost prefer an SP. I guess the only drawback is the lack of a headphone port. And the lack of the SNES X & Y buttons to accomodate a lot of the ports to the Game Boy; a problem the Micro is also guilty of. Both handhelds also have the A & B buttons positioned too awkwardly. They should mirror the angle of them.
The Micro reportedly has a better screen regardless of the SP’s “upgrade.” How can the screen be smaller that the SP’s native resolution but have a superior quality? I’m guessing they use physically smaller pixel dimensions.
