One of the biggest disadvantages of browsing the web via the iPad is its total lack of Flash, which makes it not that web-friendly. Apple claims that Flash sucks, that it uses enormous resources, that it is slow, it drains battery fast and many others. That's why they probably won't ever accept Flash on the iPad.
Actually, Apple is that one which sucks here, because Android shows that Flash can run decently on smartphones. OK, without counting on what's on YouTube, I can tell you that Nexus One is compatible with 99% percent on what's out there (yes, on the internet), and on over 90% of all websites containing Flash content, Nexus One is capable of playing that content smoothly.
Returning to iPad and Flash, there's a way of installing something like a Flash, named Frash, on it. But firstly, you need to know that you must have a jailbroken iPad. And you can jailbreak it only if you're on iOS 3.2.1 or below (sorry if you're on 3.2.2). For the right firmwares, just use http://jailbreakme.com/ (I hope I don't need to tell you that you're doing it on your own responsibility).
Then, after you finished jailbreaking your iPad, you must start Cydia, go to Manage | Sources, and there add http://repo.benm.at . After you've done that, just search for "Frash" on Cydia. Install it, and, bingo, you have....Flash, on your iPad. You just need to type on what's Flash content on websites in order to display it, but, unfortunately, it isn't as compatible as it should be.
I mean, stuff like ads work perfectly, but where we are talking about games or videos, you'll be disappointed. Mainly, they won't work at all. So, even with this trick, iPad's style of browsing is still far away from where's Android's browser.
