Lately I’ve been using the iPad2 to read at night instead of the ASUS Transformer. While they both have small annoyances, the iPad is extremely frustrating when it gives you the notice: iCloud Backup has not been done in two weeks. The dialog gives you an OK button you can click, repeatedly, and it never goes away. You have to turn your iPad off and back on again to get rid of the notice and do a backup. This means you have to hold down the power and home button, ignore the swipe to reboot, and finally let go when it powers down. Other people have experienced this exact problem for quite a while now and it still remains to be fixed.
