I said it before and I'll say it again: wave solved all of the wrong (easy) problems of communication and failed to tackle any of the hard problems. The result was a highly polished mashup of existing communication forms based on cutting edge technology that made for an excellent demo but a very poor (or at best niche) product. See also: the Segway.

P.S. Re: hard vs. easy problems: Wave tackled some hard challenges in the implementation space, which I think may have led the engineers into thinking they were building something innovative and worthwhile. However, the important bit is whether or not you've actually solved anything in the problem space.
