Sony Ericsson has never impressed us much with their past Android releases. Often weighed down by slow software, devices like the Xperia X10 just didn’t provide a good enough experience. Alas, it looks like Sony Ericsson might be getting its game in gear with its new Xperia Arc phone. It’s remarkably thin and light at just 8.7mm in depth, and it feels much faster than the graphically-intense X10. Not only that, but it’s coming with Android 2.3 out of the gate, possibly in an attempt to shake their reputation as laggards when it comes to software updates (the X10 will never see Froyo, as we learned today). The Arc also touts a 4.2″ display SE is called the “Reality Display”, but in reality (pun intended), it looks not much better than any ordinary LCD. They even claim that the Arc is using an engine from Sony’s Bravia TVs to provide a better viewing experience, but switching the setting on and off seemed to make no noticeable difference. Beyond that, you’re looking at a 1GHz chip with 512MB RAM and microSD expansion. No word on release date or carrier.
