The Wii U browser is one of the best ones ever, with a very high HTML score, and Nintendo has detailed its official specifications on their website.
It runs on NetFront engine, the same one that the 3DS, PS Vita and PS3 run on, and considering the awful scores for the Sony systems, Nintendo has found a way to utilize it really well.
Wii U comes with a browser that lets you browse the Internet from the comfort of your couch. No need to interrupt your favorite show—browse purely on the GamePad while your program continues on the TV.
You can also pause a game, launch the browser to search for tips on the game you’re playing, and then re-enter the game right where you left off.
