Great points. It is interesting to me how little "slack" people developing wholly new technologies get. Even among tech people. It ends up being "meh, it's ok but - doesn't work yet" when I would have expected more "I know how I could improve this to get it to my expectations."

Quite frankly I think this is due in large part to how much most companies hype it.

It's tricky though, because if you don't hype things - anything really, you never catch anyone's attention - and this applies to all things unfortunately. Even wikipedia had a shitload of hype in the early days.
