I am fed up with iOS7 on my iPad Air. I don't have a problem with iOS7 in general, its the bugs that really irritate me. Safari crashing ALL THE TIME is ridiculous. I also hate that the tabs constantly refresh so I have to try and find where I was on the page previously. I never had any of these problems on my iPad 3 running iOS6. Browsing the web is on of the more basic functions you would expect it to perform. Certain app icons go darker randomly and only go back to their correct colour when opened. Using the gesture to bring up the multitasking sometimes causes the icons to go into jiggle mode.
I haven't noticed Safari crashing ONCE on my iPhone 5 or iPad Mini, however I do browse on them a lot less.
My issue is, even if 7.1 fixes these issues, months of ownership of the Air has been a very degraded experience. Browsing the web on the Air is a much less enjoyable experience than I used to have on my iPad 3. However I am reading that the crashes still exist in 7.1 so I'm not too hopeful of a full resolution and really do believe now that the lack of ram is a contributing factor.
Don't get me wrong I'm not throwing my toys out of the pram and declaring a move to Android. I do however expect a seamless browsing experience on the latest model of an expensive Apple product. Not impressed and I am generally a big fan of Apple's products.
