Wow... just got my invite... Just using it in google chrome, an amazing experience... I can see what they mean as it could be a real MS Sharepoint killer... genuine new ideas... I've seen a lot of web 2.0 stuff and this has a real web 2.5 -> 3.0 beta feel to it. If they can build applications like this in the browser.. . then the compute cloud model is sure to succeed... I just want my gmail to appear in there now.
