yes for a plane ride or car ride
yepparuni :P
Anything marked as a 'DS' game will work on a DSi. There are only a handful of DSi-exclusives, and only one or two are available outside Japan. They all rely on the DSi's camera, which the DS lacks and is therefore incompatible with the regular DS and the DS lite.
They are barely any different. The DSi XL has better screens and a longer battery life, but it's not easy to carry because it's much bigger. Since the DSi is cheaper, I would recommend that, unless you have problems with your sight, or if you would use it regularly with others (the XL is designed for other people to watch you play)
you cannot get a dsi with dsi points
yes a dsi charger fits a dsi XL and a dsi XL fits the dsi
UK: DSi - £129.99 Dsi XL - £169.99 - £189.00 US: DSi - (approx) $149.99 DSi XL - $189.99
The Action Replay is for the Nintendo DS and the Nintendo DS Lite, while the Action Replay Max (or, sometimes called the Action Replay DSi) is for the DSi only. The normal Action Replay will not work in the DSi, and vice versa. I hope I helped! ('u')
Yes, the DSi charger is the same as the DSi XL.
No, the dsi XL has a bigger screen than the dsi.
There is no "DSi lite" console but if you mean the DSi XL, it is fully compatible with DSi games(although you'll have to buy them twice if you want a copy on a DSi and a DSi XL)
I dont really get what your saying. But if your saying how to get internet for the dsi. Go to dsi shop > dsi ware > free > DSi internet
