You must not been using wifi, or maybe is better than mine, cause wii u browser spits hot garbage.
The browser itself isn't bad or anything, is just so many problems, use it too long and it doesn't return to home menu, very bad if you have a game on pause, watching videos too long and then video player have problems, randomly disconnect from access point and the wifi all together stops working, a simple reboot of the console can fix but is annoying to have to do that. Trying to open links in new tabs by holding down the object on screen only works when it wanna, there is more but i guess i can save it for later.
Now if the switch had browser, since is 5GHZ AC, i could be happy about it. Also maybe having chrome cast or some kind of screen casting would be nice, if is nvidia based it should either be android compatible with chromecast or something maybe even display game on pc like how that geforce experience can use shield to play games stream from pc. Have a better video player and maybe even audio playback to listen to audio files like soundcloud or bandcamp. Or how bout normal apps like any modern tablet has, a video player that doesn't only work with specific formats, or video player that works with any format as well, how bout some media apps that put that nvidia power to the test. If anything a few ports of some android apps like xm player or Droidsound, a professional picture editing software, or even a built in video recording soft ware like playstation and xbox has or even broadcast to twitch or youtube, now that be nice.
