As for the NGP; there isn't a comprehensive list of what functions the device covers, so it's pretty pointless to make blind assessments in that respect. "If the 3DS is basically an enhanced DS with 3D, then the NGP is just an updated PSP" statements are pretty childish.
Presumably it will do all a smart phone will, with more processing power and memory tailored for game use, minus the ability to make phone calls on a cellular network, which is not, nor never was the intended purpose of the device.
Beyond that, and some of the most if not the most impressive portable games to date, I am expecting to see some interesting applications of the hardware itself in the form of augmented reality games/functions (mapping, live navigation, etc.) social networking apps, and some heavy duty media functions.
As a portable device, the high res OLED display itself is what may make me favor the device for portable media functions alone.
I already know about the initial release games and future releases, so about the only thing that could kill the device in my mind would be the price. If it's $400, I have to say unless the 3G data plan is excellent and the built in web browser is better than the iPhone's, I won't be buying one initially.
At $250 for the base model, it's a given purchase even if I use it for nothing but NGP specific games.
