The Icon pane not only looks the same as iOS, but regarding the layout also Launchpad in OS X. I wonder how much design change we will see in Mavericks. So far there don't seem to be that many design changes in Mavericks.
I think, what he means is: there are virtually no more stories about the Mac. So ignoring iDevice/OS stories would mean, ignoring AI almost entirely – and I agree. It would be nice to have more (in depth) stories about the Mac and Mavericks.
A bit short for a feature – and somehow there isn't much on 'sharing buttons' as promised in the header.
And when you remember Steve Jobs quote 'We made the buttons so nice, you want to lick them.' I can see why people find the new UI controversial. I'm not sure whether people feel compelled to lick the buttons in the new UI.
OK, I agree with you on that criticism. But just because you have a point doesn't mean it should be free.Double dipping is probably the best description I've heard for this so far. Data supplied by a shared folder should not be eaten off your quota.
