We’re used to the Xperia smartphones being wide and not so elongated as the following concept. This is the Sony Ericsson Xperia X21, a device created by Long-Nong Huang and a handset that uses a 4 inch Reality Display, plus 1GHz CPU.

Other details are not known, but the form factor and design sure remind me a bit of the Nokia 5800 XpressMusic. Android is pretty much a given on this phone and I have to wonder if there’s a potent camera at the back or not…
