Sony Experia U is a beautiful bar shaped mobile powered by Android 4.0 (Ice cream sandwich). I was surprised by its superb camera quality and speed. It has micro USB port so by using a connecting wire you can use any USB device on it, they call it OTG (On The Go), you can run pen drives, external hard disks or any USB device. The battery lasts for at least 2 days if it is tweaked for optimum power consumption. It never slows down while using multitasking.
Only 4 GB internal memory and no SD card slot. 4 GB is too small now a days when Android apps are too heavy and takes huge space.
