Speaking from personal experience, I would not recommend this update at all. First the interface changes from black to white, and while eventually you might get used to it, it is a really blinding change at first. But most importantly, NOTHING works for me anymore. Everything crashes all the time, and that's not limited to apps. I had to turn the sound off on my alarm because my phone would freeze when I tried to hit snooze in the morning and the sound would just keep going. Even if I only have one app open it takes forever to load and I constantly get "[app] is not responding" messages, including "Xperia Home is not responding" - seriously, this error comes up even when you try to close your apps. If it can't load something fast enough, the screen just decides to go to black and you can spend minutes clicking and holding the unlock button with nothing happening. And while the world might be spoiled by the technology of smart phones, sometimes my phone would even crash when receiving a phone call, meaning it was useless even for its most basic function.
I miss 4.1.2 so much. Every day I think about filming myself using my SP because I'm sure someone out there would find my frustrations amusing.
