I have an iPad 2 and an HTC Evo 4G LTE (Android phone).
I would, sadly, rather browse the web on my cell phone than on the iPad 2. Why? Ad blocking.
This is trivial on my Android system, relatively speaking. I rooted it and installed AdAway, and then I'm done. No significant advertising in any app or when I browse the web. Problem solved! Amazing speed, no popups, life is beautiful.
The iPad, despite a great interface, is horribly crippled in that I can't control what it does when I browse the web. It grabs every ad, talking ones, animated ones, popup ones, hijacking ones, you name it, my tablet is the advertisers' whore. I only use the iPad for games anymore. And I rooted the iPad and STILL can't stop this crap. Chrome for iPad has no adblock. Neither does Safari.
If there were a way to do the hosts file trick on the iPad, I would love to use it more, but as it is that thing makes me angry every time I pick it up.
