Original DS is bulkier and the pixels in the top screen like to die for no reason till you can't see anything.
Lite is smaller, but the hinges between the top and bottom screen like to crack.
i is like a lite but made of sturdier materials. Shoulder buttons like to die more than the others.
Don't know about iXL.
The older they get the cheaper they get.
i and iXL don't have GBA slots so if you want to transfer your pokeymanns from the older games that isn't an option.
