My iPad 2, running iOS 7 gets disconnected in certain WIFIs quite often.
My iPhone running iOS 6 stays in the same network without any problems.
Since Mac OS X 10.5/10.6 and iOS 5/6, more precisely since roughly half a year, perhaps a year, before Steve Jobs death, the quality and usefulness of Apple Software goes downhill rapidly ... 10.7 does not even offer a hotkey or a menu to switch desktops. And how to activate multiple desktops, you need to google for. I guess a huge amount of people who never had 10.6 don't even know that 10.7 and later supports multiple (virtual) desktops.
Support for AppleScript, for Apples own programs, like TextEdit, is down to a bare minimum ... you can not even insert a clickable link into a text document via the applications API (not sure if that ever worked, though).
My Application lost the ability to search a few days ago, also the intelligent folders (which I rely heavily on in my business) stopped working. A restart of Mail.app changed nothing. I had to reboot.
Backups to time machine, don't work minimum once a week. Error is: (insert computer name) bundle in use. I wonder by whom? Usually I have to reboot the time machine, which you only can do by unplugging it from the power: which is a bad idea for a device/appliance containing a hard drive. (This is all 10.7 on a MacBook Air)
The back ups for my other laptop, running 10.6 got lost half a year ago. Timemachine gave an error: incremental back up not possible, need to make a full backup. Wow, never had I assumed that implies all my old backups are gone.
I could rant for ever ...
MS I mainly hated because the UI is not useable, and the random bugs that showed up REGULARLY.
Now I start hating Apple, too. At least the UI still works better (for me) than Windows.
Probably it is time to build up my own unix based backup solution and write my own apps for basic stuff like Mail and Web. I can not get it that it is still impossible to freeze a browser tab that is in the background completely ...
A few tabs open in Chrome and Safari and the laptop just runs 3h instead of the 'normal' 10h.
