@Noel Thanks. That was a great post.
Release to Manufacturing (RTM) version of Windows 8 is the full version of Windows 8. It will be patched and upgraded along the normal path like all other versions of Windows. This differs from Alpha and Beta versions that could require re-installations rather than patching.
While I don't isolate things to a single variable, I think my personal experience relevant. A bit like a social science or a political pole, it could be misleading or misinterpreted, but it isn't entirely meaningless.
I'm a pretty talented computer user. I'm a long way from a star, but I make a living at it. I do live on a budget, but I have been an early OS adopter since XP. I installed Beta of Vista and 7 before installing RTM versions before they were released to the public. I get this for free because of my day job.
There have been OSes which I struggled with more. Windows 8 isn't one of them.
@Silicon_Audio I don't love the fast boot feature personally. It has taken some getting used to. Where I used to be able to shutdown with my M-Audio Fasttrack Ultra plugged in and on, I now have to be sure to turn it off first. That said, I don't really shutdown anymore - just hibernate or sleep. It's hard for me to remember to turn off the audio device because I'm usually tired and racing to get to bed as I bounce down a last track, export, use Lame to make an MP3 and post it so my friends can hear. powering down my usb powered interface doesn't always come to mind.
Also, I have been using Cakewalk since XP, so for all those Beta, RTM and early installs, I've been installing Cakewalk and testing.
