I've bought, or received as a gift, just about every single iteration of Nintendo handheld:
- The original gray brick (decomissioned)
- a green Pocket (around)
- a lime green GBC (still working)
- a "glacier GBA" (stolen)
- silver SP (still working)
- DS, the fat original silver one (I play it on a regular basis)
I agree with t0rm3n7 that the micro is retarded. It's more like a functional keychain than anything.
