I still consider the original GBA superior to the SP. The horizontal layout was a beautiful merging of handhelds and controllers; I'll never get why Nintendo went back on it so fast. But they seem to have come around now, as the DS and the Micro are arranged horizontally.
I have a Micro, and it's an absolute joy to play -- I just wish it were backwards compatible. You can't play any pre-GBA games on it or even use a standard link cable. Like Mav, I still play GB/GBC games (most recently Gargoyle's Quest, and the Zelda Oracle games are in the mail), so I keep my original GBA around for that and the occasional GameCube linkup.
By the way, those of you who don't read my LJ will find
this post topical.
