I’m only 15 minutes and and wow this is great!
I was at the Google I/O event when they announced it and current have a dev Wave account. Right now I’m not that impressed. I’ve tried to use it numerous times but right now its still a bit light on features. All the cool stuff they showed in the presentation just doesn’t quite exist yet in the real Wave. I’ve got high hopes for the final release but right now its totally a let down.
