if you can why not ?

depends on price, tbh.

definitely as the 'New' series of 2/3DS have more ram and i believe double the cpu power? but it's a much more capable and faster model than the standard 2/3ds's :) - especially for homebrew apps and emulation

i dont have one but the 2ds xl has so much more than the 2ds, such as a foldable screen, and its bigger and comfier for your hands while still portable!

i have a 2ds xl its feels like its so fragile and gonna breack any second and the screen is so floppy so i would recomend to either stick with ur 2ds or get a 3ds
