A functional OS is all I would like to see. iOS 7 is garbage and is the worst software Apple has released since System 9.
Still broken in iOS 7 at least on the iPhone 5.
Bluetooth connections aren't stable. Sometimes you have to turn Bluetooth on and off multiple times before it will connect to a device.
Music app constantly crashes, skips songs, deletes songs, won't play some songs that are transferred to the phone, duplicates songs & albums, gets stuck on cover flow and doesn't switch back until you force close the app. Playlists removes songs that are on your phone that still show up under Artists or Albums. Playlists will play songs from different lists at times. Switching to another app or unlocking the device while music is playing will often force the last couple seconds of a song to repeat before the song continues.
Transitions are glitchy or replay twice when unlocking the device from the Notification Menu.
Keyboard in Safari is eye straining and blurry, especially on iPad.
Safari, Mail, Music, Settings, Messages, Phone, Contacts, Remote, Reminders, all have an eye straining blurry White color that bleeds red pixels to create almost a pinkish hue. (inverting colors or lowering brightness to it's lowest setting is not a fix)
Home Button sometimes takes multiple presses to wake the device. At times it just reboots it if you press it to much cause it won't wake up.
Saving images from the Web tend to bring back thumbnails and pictures that were previously deleted.
Battery life is worse than all previous version of iOS. Even with Location Services off and brightness turned all the way down.
Syncing with a computer is laughably bad. Purchases from the device don't always transfer. If they do transfer they are often removed from the device, so you have to resync the device after you tell iTunes to re-add said purchase back.
*** If Apple loves Windows Phone so much that they copied the look and feel to it (Microsoft style glitches and all) then why didn't they just give us Windows Phone 8. ***
