For a while now I have been contemplating getting the Asus Prime which appears to be a pretty good tablet. Battery life is exceptional, the GUI works fine, and the keyboard attachment seems helpful. I've watched a lot of video reviews, mostly Cnet, and they all give it a fair rating but occasionally someone says it sucks, very rare. Before a make this $500 commitment, $650 if I get the keyboard attachment, I was hoping on getting a second opinion. Is it worth the money or is the Ipad2 a better product?
