Re: windows 10 mobile
I took the gamble and put it on my 1520, I hate the words "Daily driver" but I suppose by how the rest of you use the phrase then it is, as apart from my crappy Android work phone (And I only use that for work emails and to track our cars) my 1520 is my only phone.
I can only go be my own experience but I am more than happy and as long as a hard reset is done, it appears very stable.
Having just read the latest about what phones get "Official" upgrades I would put my wife's 830 through it this evening, but my wife doesn't cope to well with change so it's probably best I wait until the equivalent of the RTM build, but only so she doesn't get pissed off with me saying "Update time".
