I was able to put this into action last night and fool around with all of the features last night with a friend. It really is a huge upgrade over email. The only thing now is the adoption process that will take a long time. Facebook didn't become great until non-techie friends started using it, and that's how wave will be as well, at least for myself. Getting people to switch emails is going to be much more difficult than getting people to sign up for a website. But, it's really nice, if you don't have an invite let me or somebody else who offered know. Wave isn't just for techies, it's a better way to do email.
