Sony Ericsson Xperia X10 mini, but frankly, the X10 mini pro here comes as a bit of a surprise. The sets are nearly identical with the exception of launch colors -- the mini will ship in black, pearl white, lime, pink, red and silver, while the mini pro features just black and red a minuscule size difference, and the pro packing a QWERTY keyboard.
Sony Ericsson Xperia X10 twins run Android 1.6 (though with the time to market gap we've come to expect from SE this could change) on a 600MHz Qualcomm MSM7227 and will ship in both North American and global 3G variants with quad-band EDGE, WiFi, Bluetooth, and a pack-in 2GB microSD card
The 2.5-inch (240 x 320 pixels) capacitive touchscreen is scratch resistant. It is lightweight and can fit just about anywhere. A 3.5mm handsfree socket is located at the bottom near a micro USB 2.0 port neatly hidden by a flap. Volume keys are on one side just above the camera button. A hot swap for the microSD card as well as the SIM are located under the rear panel which incidentally comes in a variety of colors, three of which are included in the package. The battery of this handset cannot be removed so if the handset hangs there’s no quick fix.
The Android OS (v1.6) runs on the Mini Qualcomm MSM7227 600MHz processer making the UI extremely zippy. Sony Ericsson’s TimeScape UI (seen in the X10 ) works well here. The Four Corner UI is convenient and simple to set up and use. It offers multiple desktops but can only have a single widget per page. The UI is smooth and easy to navigate easily with just your thumb.It is well designed. And looks and feels very much QUALCOMM Brew Platform rather than Android.
The player is simple and capable of providing loud and clear tones even without any settings. The Infinity button enables you to get additional information on each track from corresponding YouTube videos to other data with the press of a key. The FM radio did not work out too well. Reception was not very good even in areas where I usually get great reception. TrackID is also available for getting data on songs via external source or the radio. The handset supports 3GP and MPEG4 files even if they are in iPhone resolution.
