The Sony Xperia U is a petite, budget Android blower that packs a
dual-core chip into a dainty, pocket-sized format. It boasts a strip of
coloured lights that pulse and change as you swipe around. It\\\\\\\'s an
eye-catching feature although jazzy mood lighting won\\\\\\\'t be to everyone\\\\\\\'s
Another colourful flourish is the U\\\\\\\'s swappable end caps. These let
you personalise the look of the phone, turning a monotone blower into a
snazzy two-toner, should you so desire.
