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
Two Shortcuts for App Exposé
If you want to see all the windows for a particular app via App Exposé, there are two hidden shortcuts. For either, start by pressing Command-Tab to bring up the app switcher. Then, while still holding down the Command key, press either the 1 key or the up arrow. That puts you into App Expose mode, with all of an app's windows showing, and recent documents in a row across the bottom of the screen. Let up on the Command key, and then you can press Tab to cycle through all the running apps.

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.
