An interesting point to make about the CPU choice. A lot of people are making the comment that this is a keen example of Nintendo "cheaping out" and I think that comment is a little unfair. Just because those two ARM11 cores run at a meagre clockspeed doesn't actually mean that they'll be any cheaper to manufacture, they'll have the the exact same silicon budget as standard ~600mhz AMR11s as featured in most previous generation smartphones.
They're literally the same chip, Nintendo are just clocking them lower to conserve battery life and the fact there's two of them in there actually means they've actually dedicated a fair bit of silicon to CPU resources. They'll be fully capable of running at much higher clockspeeds and that's something we might actually see further down the line just as we did with the PSP. They had plenty of cheaper options than two full ARM11 cores available and if BC really did demand a dual CPU setup then Cortex A8s really were always out of the question imo. That would have meant that Nintendo dedicated two times as much silicon to their CPU solution than even the highest end smartphone currently on the market.
No, this is all about battery life first and foremost, if 266mhz was the highest clockspeed they could get away with while maintaining a 10 hour battery life then so be it. There'd have been much more bitching if the 3DS ended up with PSP or Iphone levels of battery life when playing 3D games.
The one area they definitely did "cheap out" in is the size of the main memory pool. 128MB really wouldn't have made all that much difference to Nintendo's bottom line but if this device really isn't going to offer many "non gaming" functions and Nintendo really don't want to design a nice ingame OS then its understandable why they made the choice they did. I feel it is rather shortsighted personally but if their vision for the device is set in stone then it really isn't a choice that is going to hamper that vision as much as some assume. 64MB of RAM is still quite a lot for a dedicated portable gaming device, Xbox level textures should more than suffice for a 3" screen and I really struggle to believe that this level of hardware could have made any real efficient use of more than 128MB.
