Buy/Try/Skip - The answer is a definite Buy!
I've just bought it and it works great. You do need a high end connection though, as it uses remote SSH servers.
I can watch newgrounds, play flash games, and more! I am very impressed. Your only thing I'm worried about is Apple taking down the app because they can't patch the flash exploit because it's just an SSH Server and not really a hardware or software exploit.
Love the browser. It's worthit.
