My iPad mini Retina has not crashed at all in the four months or so I've had it. My iPad 3 rarely crashed. Perhaps 3 or 4 times in the 21 months I had it. My iPhone 5 has only crashed 2 or 3 times in the 10 months I've had it.
Yes, Safari app crashes a lot on all my iThingies. It sucks on my Mac too! not as bad as the old
CyberDog internet suite Apple introduced back in the mid 1990s though! That was horrible. Of course that was pre OS X when the Mac OS was getting very old and outdated.
Oh well, Mac Rumors is reporting that iOS 7.1 should be available any day now. let us hope that it brings resolution to several issues people have reported.
