Smartphone shoppers with an inclination for Windows Mobile are about to be faced with a really serious problem later this year -- our favorite kind of problem, in fact. In the QWERTY arena, the Sony Ericsson XPERIA X1 and various incarnations of the HTC Raphael are setting up to go head-to-head in a battle royale (ironic, since both are made by HTC) that will pit VGA against WVGA, WinMo 6.1 with TouchFLO against WinMo 6.1 with Sony Ericsson's custom "panel" interface, and 7.2Mbps HSDPA against 7.2Mbps HSDPA. If that ain't an even fight, we don't know what is, and we think that it'll probably come down to carrier availability for a good number of folks that are hoping to score one on a contract discount. Anyway, the::unwired has unearthed a full spec sheet for the T-Mobile-branded version of the Raphael, the MDA Vario IV, and the hearty 256MB of RAM and 512MB of ROM are just two of the many line items worth drooling over. A little competition never hurt anyone, eh, Sony Ericsson?
