Sony Ericsson Xperia Active

For example, the inclusion of swipe-to-type functionality in the onscreen keyboard is a real bonus. On the Active -- which has a quite a small display -- this proves to be invaluable. We also like the fact that you can now take a screenshot of your phone's display via a menu command. Apple's iPhone and iPod touch have boasted such a feature for ages, but very few Android devices have it.

Speaking of the small 3-inch screen, we're pleased to report Sony Ericsson has made some changes to the user interface to make it more manageable. The 'smart corners' concept -- first seen on the Xperia Mini -- is back with a vengeance, and it allows you to tag four different application shortcuts to each of the display's four corners.

It's a fantastic system that not only saves time, but makes the phone's UI feel more intuitive. You can have all of your communication shortcuts -- such as text messages, email and your dialer -- tied to the top-left corner, while your media links -- music, YouTube, gallery and camera -- can be pinned to the top-right.
