Let's see, where shall I start...I have to say, if you're that unhappy, why are you still using Apple products? That's the big question here.
Desktop: Windows XP went to Vista was a big turn off, and then I saw the Mac OS X Leopard where everything just works and looks beautiful. Switched over and got Snow Leopard on the day it came out and everything worked better until now.
Mobile: Used to use Symbian and then tried Android which was a big upgrade. Tried iOS 5 once and it is much easier to use than Android and stayed here ever since (still have an Android phone at the same time). Got iOS 6 on first day and had no issues with Maps because my car has built in Nav. Everything worked like a charm until Apple start breaking stuffs with iOS 7.
Meanwhile, Windows 8 is a mess so switching back is a no go...
On the other hand, the other smartphones are worse...
So there is really not much options now.
