More challenging games!

and a decent browser....

Every Advance Wars game would be integrated into the consolo.

3 screens?
1 big screen in middle, 2 smaller ones on the sides.
big hands compatible with fully opened.
All 3 screens can be combined as 1 big screen depending on games.
All 3 screens would be touch screens.

And lastly, it should detect licking and response with an electric shock to prevent people from drooling over it.

@seriousWB, that would be my choice too.

All DS Lite buttons would be the exact same as the DS Phat buttons. Then the DS Lite would be perfect IMO.

Force all games that do not make innovative use of the touch screen to be backwards compatible with the GBA, so that I can play the 2D platformer/adventure/strategy games on my Game Boy Player on my TV. I can't stand playing handhelds.

Make it a PSP, lol j/k.

Probably the touch screen, not a big fan.

The PSP is uncomfortable, but its demographics are clearly shown in its design, and the exact same can be said about the DS.

The DS is nearly impossible to hold in your hands, forcing you to lie it down on a surface and stab the screen with your stylus.

Support for WPA wireless connection. Other than that, nothing really.

Only from looking at a DS, I would say I would prefer a wider screen at the top, but it may make more sense to have the same screens on both. However, what I would not like is no buttons and only touch screen, you can't get angry at touch screens as effectively without damaging them
