I would agree with most of the other posts here. I was spending quite
a bit of time in the Wave Sandbox at first, but the more I play around
with Wave, the more I realize it is "not ready for prime time." As a
concept, it is very much an Exchange and other webmail clients killer,
but in execution it is not very intuitive, doesn't work very well, and
lacks sufficient information and access to be able to do much with
it. Even the limited tutorials tend not to work when you try them
out. This is a pattern I've noticed a lot with new releases from
Google - more hype than actual functionality. I would love to see
Wave succeed (and Chrome OS and Android), but I don't think any of
them are really ready for the average user. (They don't even seem to
be ready for the average developer.) In the meantime, I'll keep my
toes in the water to see what changes and try out the occasional idea,
but I'm not going to devote a significant portion of my limited time
to an API that's not there yet.
