Gamestop (EB Games) sells 3DS at MSRP, which is as of October 2013, $169.99
It won't fit in a DS or a DSi, there is a tab on the 3DS game to stop it.
Not currently. EDIT: it is possible to create videos on a software called "inchworm animation" just look it up. However it its basicly stop-motion animation and it cost 4.99 in the nintendo eShop.
No, they cannot be played because of the motion censors they have for the portable platform, however you can look forward to the Metal Gear Solid series for the 3DS ^_^
At Game Stop.
no, when the 3ds is charging it will charge until he has full charge and then he will stop charging, so you can leave your 3ds at charge at night and nothing will happen to him except he will be charged of course
You need to connect the SD card from your 3ds and plug it in the computer and just paste the songs to the First folder. You can only hear music from the nintendo 3DS sounds application.
Lots of new DS games have been released since the 3DS came out. They will stop eventually, but not yet.
