If we're talking about what we'd like to see added/altered in the amiga chipset should it be released now, then i'd think that a handheld device would be a pretty good target.
Or to put it another way. The GP2x only runs at 200Mhz, and the PSP is clock limited in software to 222MHz. So a 220Mhz Coldfire CPU and an upgraded AGA chipset + 3d hardware and you'dmhavea great little portable gaming system.
It doesnt have to be powerful 3d hardware either. The PSPs gpu is utterly woeful, it doesn't even support multi-texturing, urgh.
No just add better chunky support as Dennis was saying he'd like to do to the MiniMig, a low-power portable gpu and a ColdFire CPU and there'd be a really desirable portable machine with all my favourite games on it... ah *off-in-fairytale-land*
