I'm guessing you did not see the keynote or the talk about wave extensions, gadgets, and robots. Wave is a super aggregator, and I expect it will not be another nuisance to check.

Think of wave as a mashup of iGoogle and Gmail on steroids, with supreme customizability.

The recent explosion of labs in Gmail is a hint of what will be coming as developers sink their teeth into wave.

Disclaimer: I attended Google IO and saw the demo. I may have had some Google koolaid without my knowledge.
