About bloody time, too!! Most of this stuff was announced in June. It is very disgraceful making the public wait so long... Especially for devices like the new Mac Pro. Just think of how much income Apple has lost by delaying the release of such a device like that. The same with OSX Mavericks and IOS 7.
Clueless. When those things were announced in June, they were announced for either fall or by the end of the year. Not a single one of those is late yet, all the ones that had announcements are shipping when Apple said they would.
The two OS updates had their first betas shipped at the time of the announcements. For those, they absolutely need a few months in beta to work the bugs out and let devs update their apps to the new OS. And the Mac Pro was announced having upcoming Xeon chips, those chips only started shipping recently.
Sounds like you only read the headlines on those announcements earlier this year and totally missed the details. Pay more attention next time.
