Powered by a 1GHz processor and a 4″ WVGA display the Xperia X10 is certainly a potential hit for Sony Ericsson only if they can get the software part right (the pricing aswell). After being written off by many popular journalists / bloggers wrt to the sluggish performance during the official launch announcement, a newer video has emerged with better software built.
The phone looks smooth and much more promising now. The launch date has also been leaked as February 2010 now. Video downstairs.
