"the freedom and the elegance of the Mac is gone forever in this OS update."
Why?
You could buy the USB to do a clean install or simply via the recovery partition as you mentioned. I don't see anything wrong with that? Also burning an image is not Microsoft-y? It's not obvious but it's easy to find out how and easy to do if you wanted to do it. Simply secondary click > show package contents > find InstallESD.iso open in disk utility and burn.
I could go on, but what is the point.
