Android Devices in the Market

Android devices come in all shapes and sizes. As of late November 2011, the Android OS powers the
following types of devices:
➤ Smartphones
➤ Tablets
➤ E-reader devices
➤ Netbooks
➤ MP4 players
➤ Internet TVs

Chances are good that you own at least one of the preceding devices. Figure 1-2 shows (left to right)
the Samsung Galaxy S II, the Motorola Atrix 4G, and the HTC EVO 4G smartphones.

Another popular category of devices that manufacturers are rushing out is the tablet. Tablets
typically come in two sizes: seven inches and ten inches, measured diagonally. Figure 1-3 shows the
Samsung Galaxy Tab 10.1 (left) and the Asus Eee Pad Transformer TF101 (right), both 10.1-inch
tablets. Both the Samsung Galaxy 10.1 and the Asus Eee Pad Transfer TF101 run on Android 3.
In addition to these popular mobile devices, Android is also slowly fi nding its way into your
living room. People of Lava, a Swedish company, has developed an Android-based TV, called the
Scandinavia Android TV (see Figure 1-5).
Google has also ventured into a proprietary smart TV platform based on Android and codeveloped
with companies such as Intel, Sony, and Logitech. Figure 1-6 shows Sony’s Google TV.
At the time of writing, the Samsung Galaxy Nexus (see Figure 1-7) is the only device running on
Android 4.0. However, Google has promised that existing devices (such as the Nexus S) will be able
to upgrade to Android 4.0. By the time you are reading this, there should be a plethora of devices
running Android 4.0.
