I agree with the piece. The standard edition is well worth it and there are plenty of good games out for the system, including a full library of DS games. Never played some Phoenix Wright or Professor Layton? No problem, now you can. The eShop also has some awesome 3D remakes of old favourites that'll keep you busy forever.
For under R2000, this is a really great handheld to own. Do it, do it now.
I love playing Pokemon Mystery Dungeons: Gates of Infinity since I love the 3d effects on it so for Pokemon I would say the 3ds xl is totally worth it and also if you a Mario Fan too.
Umm the Wii U is portable you dont need a tv to play the games if you dont want to and there is a Pokemon game coming out for the Wii U called Pokemon Rumble U, but no release date except in Japan.
