I would argue that the ability to set default apps is much bigger than all those combined. IMO, it's a simple change that would fundamentally make iOS much more pleasing to use.
I can't say I've ever really been dying to have a WP8 style multitasking view, unibar in Safari, or yet another (limited) proprietary file transfer system but maybe I'm in the minority and these are actually big issues. Quick settings was long overdue though.
Yeah, I really really want default apps and the option to totally hide apps that come with my phone. Who the hell uses the contacts app? I don't want stocks or passbook either.
I would also like the ability to attach an image/video WHILE i'm writing an email, not the other way around.
Just got the new macbook air. This is my first time using OSX. What apps should I get? Do people use safari over chrome?
I prefer Chrome, but Safari is good too.
If you're coming from Windows and used to window snapping, you can get it (and a bunch of cool gestures and stuff) by downloading BetterTouchTool.
