Electric Pig is reporting that Sony Ericsson’s already working on a followup to the Xperia Pureness. The designer of the original handset, Daniel Mauritzson, says that the second version of the Pureness will pack even fewer “features” than its predecessor, to hone in even further on the contrast between the handset and available smartphones. There’s also been some murmuring of removing the buttons, apparently — which makes us wonder if the next Pureness might not just be a four-inch long piece of black plastic we’ll only be able to pretend to make calls on. Regardless, it sounds like the next Pureness is only in the very earliest stages of design, so don’t get too excited yet — it’ll be a while.
