As delicious as the NGP looks, I can't get myself interested enough to buy one. Although, that's mainly because I don't very much care for portable consoles.
My biggest wonder is how quickly the battery will die. All the wonderful features the NGP comes with would surely make the battery work to stay active. But then again, technology advances faster than one would think, so perhaps they have a way of making the battery live longer...? I, personally, would not like to play an NGP for a total of 3-4 hours before recharging each time.
But, other than that, it's looking like quite a powerful little device. I wish I could get myself interested in it, but... ahh well.
I ended up telling my boss about the NGP and 3DS. She saw dollar signs. Lots of 'em.
