The main screen on the 2DS is a little under half an inch (diagonally) bigger than the DS Lite, and the DSi XLs is over an inch bigger. If you're just looking for a bigger screen, getting a DSi XL would be the cheaper option. On the other hand if you're willing to settle for only a somewhat bigger screen the 2DS does have the new Circle Pad (works like a joystick; much more comfortable than a D-Pad for some games imo).
As for the 3D feature I actually think it makes some games look better (looks great in Ocarina of Time 3D, Starfox 64 3D and Link Between Worlds). That said it's not important to gameplay at all, and actually drains your battery faster having it turned on.
I still want a 3DS so I will keep looking for some good price. DSi XL here is rare and when you find one it's about the same price as a 3DS so...
