The DSi has two different cameras. It also has 11 different lenses that you can change around your pictures with. There's also a DSi shop where you can get free games with the points you get from making an account on the shop. You can play around with your voice in the sound center and make your voice into multiple people, or really anything else! You can read more information on the DSi in the instruction booklet that comes with the DSi. The DSi is awesome!
Yes but you have to buy a special card to insert into the dsi sold separately
No, because the 3DS games have a special shape that can't fit in the DS or DSi
Yes, there are DSi games that are slightly enhanced, gernally having better fps and may have features that allow the usage of the DSi camera.
It plays all the games the DS lite can play as well as special DSi games
by buying some at the Nintendo shop
No, you do not. The DSi is simply an advanced version of the DS lite. You can play your DS games and only your DS games on the DSi, minus the fact that you can download games from the DSi store.
it depends if you buy a special package if you dont then no
500$ AND you get a special secret game with it BUT i cant tell you its a secret
No just the same way as a DS Lite !!
the dsixl comes with a special charger bigger than the ds lite(and the dsi isn't much bigger) so i don't think it would work
No you need a special kind witch isn't out yet
The Nintendo DS Web Browser is a special version of the Opera Web Browser, developed in conjunction with Nintendo. There are different versions for the Original DS and DS Lite (both of which require special RAM expansion packs), and the DSi, which is available through the DSi Store.
