Watched a demo of Google wave.
Frankly, am not very excited... :-|
Somehow I don't like the idea of 'browser-as-the-operating-system', or even 'browser-as-the-platform'. I am not a believer yet. Will not be as long as the browser windows have those forward, back, and reload buttons.
Would rather like to see (desktop-)applications that are seamlessly network enabled. Without having to fiddle around with "XmlHttpRequest" or some such shit. And not using "java.net.url" or some very low level stuff either. That's just me.
