The problem with this is that the "new" desktop is fundamentally different from the old one. It's not as simple as saying "oh, just use the desktop".
> IMO, they are insistent on improving their products.
I wouldn't consider presenting users with a puzzle to be an improvement. I can pick up my iPad and instantly figure it out. I can pick up a MacBook Air with iOS-like features and instantly understand how they work. I was stunned at how much effort was required to learn Windows 8. Absolutely stunned. How exactly is that an improvement?
By the same token, I can pick up a Windows Phone 7 device and instantly understand how to use it - but Windows 8 still somehow turned out to be a confusing mess with a mouse/keyboard. Even on a touchscreen device - it's not completely clear how things work. It was as confusing to use as a Blackberry Playbook.
If you can't figure out how to use the desktop without the start button (by going to the left-right sides with a mouse movement that is even easier to do), then you really should be using the Metro UI instead, because it was made exactly for you.

1. When I got my iPad it enraged me to learn/figure-out that I had to install iTunes and connect the two.
2. You're now comparing the touch based iPad UI with mouse/keyboard driven Windows 8 Desktop UI.
2. It doesn't matter if it's apples-to-oranges as far as touch vs. mouse/keyboard - the key issue here is how understandable the UI is. Windows 7, if you know how to use a mouse and a keyboard, is completely understandable. Windows 8 makes absolutely no sense.
