By introducing mobile phones that are both compact and clever, Sony Ericsson is challenging the norm and defining a brand new offering that combines high specification features with a version of Sony Ericsson’s powerful UX platform specifically designed for smaller devices.

Sony Ericsson representatives said the designers didn't believe it would be possible to achieve the same thing on the small screens used by X10 mini and X10 mini pro, so their interface has somewhat been modified with customizable shortcuts placed in all four corners of the screen.

Behind this user interface modification lays the recognizable interface of Google's Android OS, which functions well even on such small screens.

Xperia™ X10 mini and X10 mini pro with slide out QWERTY keyboard offer an open and intuitive communication entertainment experience and build on the human curvature design philosophy debuted by the Sony Ericsson Xperia™ X10. Combining the Android platform with signature applications and a customisable UX platform, communication truly becomes entertainment with these new mobile phones. To enhance the experience, pick and choose from a multitude of applications at Android Market™ and co-create a mobile phone experience that is entirely unique. Users can go one step further and customise the home screen’s four corners and widgets to access the most needed applications for limitless possibilities.

The two sister mobile phones incorporate the signature application Sony Ericsson Timescape™ which brings all communication together in one place so users can see at a glance text messages, missed calls, and Facebook™ and Twitter updates, without having to open lots of different applications. 

The interactive music player also uses the “infinite button” to pull together all music content from the music store and YouTube™ – a smart way to search for new tracks from a favourite artist.
