Just a few things.
First of all, I'm almost positive that the stylus for the display models is much larger than the ones that actually come with the DS. Also, another input method (pictured here:
http://ds.ign.com/articles/564/564540p1.html) using a thumb pad is also packaged with the console. I used the thing personally, and I wouldn't say that it isn't durable. I don't see myself punching a hole through the screen no matter how much pressure I use.
Secondly, when you comment on the graphics, you have to take it from a completely different perspective. The DS comes after the GAME BOY ADVANCE, an SNES quality machine. This is a huge leap for the mass market in terms of graphics. Also, I wouldn't say they look ugly at all. Most of the games run at a fluid 60 frames per second, which makes them look a whole lot better than any PPC game I've ever seen. Not only that, but the DS only costs $150, and thats with a built-in chat program and demo game card. We're not talking $300 PPC hardware here. We're talking about the mainstream.
The control method you used is very archaic; although it began this way at E3, the real methods of play still use the touch screen, yet don't involve tapping at all, rather, shooting is done via the L or R button (depending on if you are left or right handed).
Sorry to be so defensive, but I've been following this thing since they first showed it. I know a whole lot about it, and I can understand why the PPC scene might have misconceptions. Either way, your opinion is your opinion.
