YES, it is known as the camera option
The Nintendo DSi is just an upgraded version of the Nintendo DS and DS Lite. The Nintendo DSi plays the exact same games as the Nintendo DS and DS Lite and only plays DS and DS Lite games. Currently, there aren't going to be any DSi games, only more DS games.
There are no 'hidden charges' on the DSi. You can buy some games from the Nintendo DSi Shop, which cost money, but that's optional.
Yep, just not GBA/GBC/GB games from cartridges. There is going to be a DSI shop for buying previous GameBoy games, but that's just a way for Nintendo to make money form old games without any real expenses
there is no new games for the Nintendo ds, its just an upgraded versionof the ds lite, so the ds Pokemon games work all the same
DSi Ware games and other downloadable content The Nintendo DSi Shop is specific to the region for which the system was manufactured. For example, a Japanese system can download DSi Ware games and other software only from the Nintendo DSi Shop for the Japanese region, regardless of where the system is being played. Nintendo DSi exclusive game cards Nintendo DSi game cards that are only compatible with Nintendo DSi and Nintendo DSi XL (and not Nintendo DS or Nintendo DS Lite) are region locked. This means game cards manufactured for the U.S. market would not work in a system made for another country. Nintendo DS / Nintendo DS Lite game cards Older Nintendo DS and DS Lite software is region-free, so you can play most of that software on a Nintendo DSi and Nintendo DSi XL from any region. It's possible, however, that future Nintendo DS software will incorporate region encoding. In these instances, these games would not work in a system made for another country.

It is compatible with all DS games apart from any that require Slot 2, which the DSi and the XL do not have. (There is no such thing as a DSi XL specific game.)
Yes, DS games are not region-locked. Any console will play any games.
Maybe not.
You should be able to get a Nintendo points card from any local game shop that sells Nintendo dsi and Nintendo wii games. Hope this helps :) .
It depends on what you like. If you like high graphics and intense gaming, usually war games or first person shooter games (or other PS3 games), you want the PS3. However, if you like portability, the Nintendo games (which are not first person shooters, or any gory games involved), and like the personalization of your handheld and like mini games (free games from the Nintendo Store), then the DSi is for you. dsi hands down.
No, only GBA ones. You cannot play regular Gameboy or Gameboy Color games on a DS.
