I do think Xperia X is as slow as my current FP2 so no go for me. Dalvik is kind of slow on FP2. And the camera on FP2 sucks. But if I should buy a new device I dont want to buy three year old HW just to get SFOS. So I plan to buy Xperia XZ. Question is do we ever see SFOS on XZ devices WITH official dalvik support? What do you guys think? Or will I get stuck in Android? I tried it out today and the Android on it is fast BUT i HATE the homescreen. I want sailfish swipe UI!!!
