iPad, Android and BlackBerry
In 2010, Apple's iPad created a tablet revolution as dramatic as it did with the iPhone. However, Android tablets have given the iPad a run for its money with numerous models from many vendors. BlackBerry introduced a tablet for its customers, which was later discontinued (see BlackBerry PlayBook). See iPad and Android.

Windows Tablets
In 2000, Microsoft introduced a tablet version of Windows (see Tablet PC). However, Windows tablets were not widely used until Windows 8 changed the game in 2012. Any program that runs on a Windows PC can run on a Windows 8 or Windows 10 tablet. See Windows tablet.

Thousands of Applications
Just like smartphones, tablets come with a Web browser and a variety of installed apps; however, a huge number of free and paid apps are available from the vendor's online store (see online app store). See mobile compatibility.
