You know that's not entirely fair considering you just pointed out a 1/3 of the time or more those you find online with your friends lists on other systems are just using netflix, hulu, etc or some browsing service. The WiiU and 3DS have those, and I'd argue in better form too, at least Netflix and stuff on WiiU since it'll cast half the junk to the touch panel on the big controller which makes things a hell of a lot more convenient than popping up a menu or remembering button commands. The failing on the WiiU end of it is that they went with a blu-ray style disc, but they again like the Wii didn't want to pay for the branding or licensing files to allow the movie discs to run to cut costs and that's the problem, you can't do movies. I'll straight up admit now if that WiiU would have run DVDs and BluRays I would have kept it because just how damn nicely it handled the likes of Netflix and the rest. The fact I could have taken it a step further and put a movie in while the kid is on Disney Junior I could pop it on my desk with the stand and watch a movie or tv series disc would have been an instant keeper for me. Nintendo and their infinite cheapness and corner cutting be damned.
The 3DS though, you can't make that argument as it doesn't use discs, Vita doesn't either. Sony learned that didn't work so well with their UMDs. THat said if you want a solid gaming box that also runs movie services and a fairly solid speedy browser the beefed up New 3DS really does it well. In a way on that one you get the best of both worlds where it's a Nintendo box made for gaming, but it also has the streaming features you expect from a mobile device for movies and browsing with an HTML5 webkit browser and gets third party games.
