biometricsguy: stop talking bullshit. ARM is quite efficient CPU, especially when equipped with VFP and a 3d accelerator with programmable shaders. Nintendo GBA and DS are both quite succesful handheld gaming platforms, both using ARM CPUs. Did you see games with pure software rendering on 16 MHz ARM7 on GBA? ARM is the most widely used CPU in embedded hardware(internet routers for example), mobile phones and pdas, where it completely replaced SH and MIPS designs several years ago. PSP games are better (in average) because of propietary graphics APIs, simpler OS and also because of much higher development budgets. iPhone hardware is not used efficiently. But in terms of performance and features even 3G is comparable to PSP or better.
Sorry for bad english.
