I got my Google Wave account invitation yesterday. After a few hours I actually found some people to talk to (this preview is still in its baby stages).
I have to say, I was impressed. You chat (and it updates) in real time. You can embed stuff like Google maps, Google searches and Youtube videos (and the list will surely improve since it seems to support Google gadgets). It really feels like next-gen email combined with a messenger
It is called a preview for a reason though. Sometimes you need to refresh the browser and at other times your waves go crazy and you can’t use them for a while. It also tends to eat up lots of CPU if you have a lot of participants and media content. But its Google, so we know its all going to be fixed really soon
Below you’ll find an embedded wave I’ve added using the Wavr WordPress Plugin (you need to have a Wave Account).

Well done Google!
