... and then trying to get back to desktop, which never worked on the first try, or going into metro interface any time I accidently put my mouse on the right edge, with no easy way to go back I mean the list goes on and did I mentioned how ugly and space wasting Metro is. But I totally lost it when I wasted almost an hour downloading win 8.1 upgrade, then wasted another 30 min waiting for computer to update files etc and then I got to the screen asking to input my e-mail. Since I don't have one with MS I pressed skip, which promptly, without any warning revert back to Win 8 and deleted whole 8.1 upgrade download without even asking.

Yes Siw, I laughed too when I saw the Pete's post; I couldn't have hoped a better example of purposely misleading and wrong information and sometimes simple lies the anti-Eight troops are spreading to falsify the facts.
Let's see that post. First what I have marked with
bold red font: If the user is not experienced enough to switch between Start Screen and Desktop by a simple press of the WIN key, or by clicking Desktop tile on Start Screen, then maybe Windows (any version) is simply too much and user should find a system better suitable to his / her capacities.
About the
bold green statement in above quote of Pete's post: Switching between Start Screen and Desktop does not happen when you bring the pointer to right edge. Never. It does not even happen when pointer is brought to left edge. It only happens when user clicks left mouse button when pointer is located at the bottom left corner. Even the Charms Bar does not show when the mouse is brought to top or bottom right without user thereafter clearly moving pointer up or down.
I repeat: Bottom left, not right edge. And no, it does not switch to Start Screen simply by bringing the pointer there. Never.
Then the clear untruth (can't use here the word I would like to), the part I have highlighted yellow. That is so invalid, false disinformation that it together with the strange "bringing mouse to right edge brings Start Screen" (real name for so called Metro UI) makes me wonder if this user has ever even seen Eight in action. There is no Skip button when setting it up, and the upgrade does not revert back to 8 without user actions and notifying the user.
If we users do not read instructions, we cannot blame Microsoft or any other company.
Let's see what happens when a Windows 8 with only Local account (no email based Microsoft account in the whole machine) is upgraded to 8.1. I did this just now to get screenshots to prove my point.
First the start situation, only one local account, no Microsoft accounts:

After 28 minutes, the over 2 GB upgrade was downloaded and installed. Reboot, 16 minutes for upgrade to set itself up, finally there:

Next screen asks if I want to go with defaults or change something small (customer feedback options and such can be disabled / enabled here):

Next screen asks me to sign to my Microsoft account, which I do not want to use in this machine, so naturally I select what Windows documentation asks me to select at this point:

Which brings me to screen where I can tell Windows I want to continue using my existing (local) account:

That's it, Windows 8 upgraded to 8.1 in about 50 minutes (including the download time),
absolutely no SKIP buttons there. Only the four screens shown above are shown after first reboot when 8.1 upgrade is applied.
Again, I repeat: Absolutely sure there are no dialogs showing a SKIP button which can cause you to lose the upgrade.
I hope those users still not sure if they want to upgrade to Windows 8 can and will use their own brain and see through this disinformation spread on the Internet.
