I'll probably buy one when I have the chance since I ditched my old GBA and got a DS. The DS is nice, but I think having a GBA micro would be better than playing my GBA games on the DS or GCN GameBoy Player all the time.
Also, I'm a sucker for the Famicom/NES themed GBA SPs, so if they do release a NES themed GBA micro, that's more incentive for me.
Lastly, Nintendo said at E3 that they were marketing the micro to a younger audience (teenagers) but it seems to me that since people are starting to think of it as a cell-phone type game system, older people (20s) might want it in that frame of mind too.
All I know is it's gonna be a bitch using the e-Reader in that thing. :lol:
