It is a competitor to the Symbian platform, Apple's iOS for the iPhone and Microsoft's Windows Mobile and Windows Phone for mobile devices all based on ARM architecture. Technologically, Android includes middleware and key applications, and uses a modified version of the Linux kernel” (Wikipedia).

In education

We didn't find any interesting application that targets the education market (but didn't do any exhaustive search)

However:

• There are many games that are somewhat educational
• Many applications (e.g. google earth, office programs, communication programes, interfaces to popular webservices) that can be used in educational scenarios).
