This could actually carve out a unique market for it's self. It does not need to drive it's own display, so it would have longer battery life if used with a battery for portability (say car/camping/holiday etc), unlike a phone. You can also take it around a mates house easily. It's the kind of thing I'd of thought Nintendo/Sony/Microsoft/Apple would aim for. Why? Because once, out of all of history, it actually looks like they can fit enough power in that form factor to not be totally obsolete in content. (IE, you could get similar for ages, but it was a C64 power when N64 was around, or Sega Megadrive power when the Xbox was around).
