The developers of the OpenSignal app have compiled information from their Android users about just how fragmented the Android ecosystem is. Over the past year, they counted 11,868 unique Android device combinations — a nearly 200 percent increase over the previous year. Samsung controls almost 50 percent of the market, with numerous other manufacturers making up the rest, and OpenSignal counted 7 different versions of Android in use by its users. By comparison, Apple has released only 16 iOS devices (not counting the second- and third-generation Apple TV), and 95 percent of iOS users are running iOS 6, with most of the rest on iOS 5. follow link
Removing Photos from iPhoto
Despite iPhoto's long history, many people continue to be confused about exactly what happens when you delete a photo. There are three possibilities.
If you delete a photo from an album, book, card, calendar, or saved slideshow, the photo is merely removed from that item and remains generally available in your iPhoto library.
If, however, you delete a photo while in Events or Photos view, that act moves the photo to iPhoto's Trash. It's still available, but...
If you then empty iPhoto's Trash, all photos in it will be deleted from the iPhoto library and from your hard disk.

Android Device Fragmentation Visualized
It's hard for developers to provide a consistent experience and make everything look good and be usable with many screen sizes. Android has tools for that.
Apple made the choice to have as few screen sizes as possible, and that was a) an oddball decision at the time and b) has proven to be very very useful for developers.
