Will people adapt to Google Wave?

Ever since Google launched it's Wave in the Google I/O, the Rasmussen brothers creation has recieved a lot of praise from critics. It is said to integrate a host of features offered by likes of Youtube, Wikipedia, Facebook etc. Google has also given a lot of liberty to third party developers to make gadgets for it much like it did for the iphonewhich is a good thing. However, a lot of people are begining to question the outright use of Wave until and unless it is openly availible to one and all. I personally found it very similar to e-mail but, that's just me.
And while it has many features that are unique and very useful on paper, the question to be asked is that whether or not businesses will start using it and integrate it into their work to make life easier. What do you think?
