PSP or DS?

[Andromeda18_]

In theory, a touch screen is great -- there's some cool gameplay that can be explored with a touch screen. But when you realize that you always have to have that stylus in your hand while you're also jumping back and forth between the side buttons, and when you put together that even in games that ignore the buttons and just use stylus play, the need to support the system with your left hand will make keeping a hand on the D-pad somewhat difficult and may also make reaching that left trigger a bit more awkward ... you can see the problem.

I think this guy's right, in theory a touch screen seems like a great idea but it's going to end up being a nuisance.
As far as price is concerned there's little doubt that the PSP is going to be expensive, way more expensive than the DS.
One of the things I see everybody complaining about is the fact that neither system is original or revolutionary. They're not supposed to be! The big deal about both system is that now there'll be handhelds with the ability to play games with better graphics.
