Well said.
To all the smartalecks out there,(ie. "Of course there'll be changes, it's a BETA, duh!") have you ever once considered that Apple has never shown such an incomplete - not Beta but Alpha - product at WWDC before? Why would you show the entire public, Wall Street, and the press something so half-baked? They had to get a quick UI change done in time so they could show off the features. They couldn't miss WWDC at any cost. So, they focused on the features and left the UX very rough.
It is very un-Apple-like to share very incomplete and unpolished software, and that is what is not obvious and why it needs to be shared.
This forum is becoming nothing but two kinds of infantile people -
"Of COURSE it's going to change - it's a BETA", and
"It's NOT going to change, so get used to it. Isn't it cool"?
Please don't be one of them.
