I have been a previewer (beta tester) since last October - for whatever that is worth. The methods of update and restart has burned me several times - with interruptions and lost work. Hence, I have reverted back to Windows 7 - which is so much easier to work with anyway.
There are so many reasons not to want Win 10, that I will make that a different post. Suffice to say - I can see no reason to move away from Win 7.
My thinking now is to run a Win 7 machine as long as I can for tasks that are only available on Windows (TurboTax, HRD, Elecraft, and way too much anti-virus stuff). For email, browsing, spread sheets, word processing, HTML, drawing, etc. - I am using Linux Mint 17.
I believe I can fix the Elecraft problem with their version of firmware designed to run under Linux. I can do my taxes online, avoiding the problem of TurboTax's in availability in Linux. That leaves HRD - of which I use an old free version and can leave it on a task designated computer (HRD will never appear for Linux, as the current sellers have their hands full just keeping it running under Windows - I hate to think what Win 10 will do to them).
This overall approach works for well me, as I have used a dual monitor system for several years.
