We've known for what feels like ages that Sony Ericsson's Xperia X1 would be based on Windows Mobile
, but we wouldn't count on the X2, X3 or X99 to just follow suit. At the launch of its digital marketing campaign
for said handset, the firm made clear that future SE Xperia phones may not be based on Microsoft's OS, with Magnus Andersson, product manager for the X1, noting that "the brand is not tied into any specific technical platform." Unfortunately, he didn't elaborate nor give any indication what other systems we could eventually see, but at least we know that there will be life after the X1 in one form or another, right?
