With the introduction of smartphones and other cellular devices, tiny screens may cause our eyes to strain and limit our ability to see images in depth. With the invention of iPads and tablets however, this is no longer an issue. iPads and tablets are mini-computers that have the capability of performing multiple functions. They can be used to surf the web, download apps, check emails, view photos, watch movies, listen to music, play games, read articles, social media, e-books, and more. Anyone of all ages can use iPads and tablets, especially children and adults who require a larger screen size to be able to view things better. The three biggest tablet companies in the market right now are Apple, Android, and Microsoft. The iPad was created by Apple, while most other tablets were created by Android and Microsoft.
