"If the target market is kids or teen gamers, will they be able to afford the price of the device plus the monthly voice/data plan?"

I know plenty of parents who give their kid a PSP+DSi, and/or an iPod Touch, and a "family phone" that may be one of those cheesy sidekick sliders for texting all day.

If parents can ditch all those and give the kid one thing (presumably this PSP phone), it would almost be like making money on the deal.
