OK, I'm starting by telling that I have no idea about how popular "Hexxeh" is, but I never heard of him until now. And it seems that he isn't very popular on YouTube, as he has only a few thousands of views. But he did something really interesting, he succeeded to run the Chrome OS on the iPad. Yes, I'm sure you know, that OS created for netbooks by Google, running on the so popular iPad. So here's a video of what he did.
This seems to be quite real, because of two reasons: the first one is the pointer, which you can see that really moves when he clicks on something, and the second one is the speed of the OS, which shows that the Chrome OS might have been emulated on that iPad. Of course that there is a lot of job to do for Hexxeh, and one of the first things he needs to do is to improve the speed of Chrome OS (if he wants to release a official version of his work, of course).
