What a nightmare this build is. Once I finally got over the 18% not updating malarkey I now have 10122 installed. Unfortunately it seems worse than the previous build: it loses wifi connection when waking up, the touch keyboard refuses to appear at times, battery life seems very poor and I get a constant spinning circle whenever I want it to restart, ending up having to press the power button to shut it down. I think I'm done with Windows 10 alpha/beta. Windows 8 runs so much better.
