First, the interface is simple but easy to find what you need. The menu consists of small icons IOS and Android style for all applications and games. You can move them using the stylus by holding down and dragging them in another box. For people not familiar with the new Nintendo (Wii U and 3DS) you may be wondering what these boxes. Well the 3DS eShop has access to the online store Nintendo (also for Wii U). You will find almost all dematerialized 3ds games and retro games like Zelda: A Link To The Past to download. They will be stored on your SD card (the one included with the 3DS XL is 4Gb is sufficient if you will not go entirely paperless (the size of a game depends a lot but I will say that we should expect about 1Gb on average)).
Otherwise there is always the option to invest in an SD card 16 or 32Gb (32 being the maximum supported). It also means to operate an SD card 64 or even 128Gb reformatting the Fat32 but I have not tested this. Anyway the whole of the eShop does not fill 128Gb.
But hey, what is most important for a console? One thing only: his library of games. And what a collection of excellent / very good games, what about again. This is definitely the 2013 console not to miss and going towards 2014, with a secure future. JRPG fan / RPG Platformers, Shoot Them Up, Adventure, Combat Simulation and even with Animal Crossing. Potentially thousands of hours of content for fans of video games.
Recently, the 3DS XL is well above the 3DS in my opinion. The wider screen 90% made a massive difference and called pixelization caused by upscaling is not super visible and do not mind really.
A few minor gripes: -the sound is too low for my taste with and without headphones, damage. I was able to rectify that with a amp (3DS XL -> amp -> headphones).
-the system of friends a few years a bit tedious delay compared to Xbox or PlayStation.
PS: As many have already mentioned, not included charger. However, you can use the charger for Dsi / Dsi XL or 3DS if you have one (not compatible DS / DS lite by cons).
I could say much more but I'll stop here. As I said before, if you still hesitate, just go there and doing you pleasure, you will not be disappointed.
