In Short

The Sony Xperia Sola is a mid-range Android device with a 3.7-inch display, a 1GHz dual-core CPU and a 5MP camera.

The Xperia Sola includes a new technology called "floating touch", which allows the screen to sense when there's a finger hovering over it. The main use case highlighted by the manufacturer is web browsing -- on the Xperia Sola, users will be able hold their finger over a web page like a cursor, before touching the screen to select. 

The phone also supports NFC, which allows it to make use of Sony's "SmartTags" to automate certain features when these are within range.
