I was surprised at how impressive the Vita browser is, both speed and user interface. The Ps3 browser kind of sucks... But it's good for playing videos (norp)

Haven't tried Nintendo's browsers.

I would love to use my Vita browser more, but when I'm not on my laptop, my Iphone 5's browser is just a little better in almost everyway.

only try on Gamepad. The 3DS one is garbage. Wii U browser is heaven

I don't have a Wii U but I've heard great things about it's browser. Seems like a feature that is literally tailor made for the Gamepad. 

What's wrong with the 3ds one? Is it a matter of power/speed or usability?
