Even worse was Google Wave. Totally unusable from the start, which is when I tried it, due to all the hype (by them) about it. Probably too JavaScript-heavy, was the reason, I think, back then. I remember reading reports confirming my guess, at the time. I was on an average machine. I bet the Google devs had quite more powerful ones, and in their infinite wisdom (not!), did not trouble to test, or even think of testing on average machines that most of the world would have.
