"The Sony Ericsson Xperia X1 is a Windows Mobile slider style phone that features a full keyboard along with something that Sony calls Xpanels. The Xpanels are essentially different home screens for your phone, they're customizable and you can get new ones as they are released. It features an 800 7480 resolution touchscreen with stylus for input, an optical mouse and even handwriting recognition. The phone itself is very well made, mostly metal, and is very aesthetically pleasing, a very sleek and stylish phone for sure."
