Worst comparison in history. Sure, pick the documents folder with the stupid heading extra, and how many power uses have that bar that large on the bottom (even then it's too big, at it's smallest setting). Win 7 can easily display 26 in that space, though they could get even more if they removed the complete waste of space that is the Organise, Share with bar. Horrible, horrible comparison.
It's obvious the Windows 7 one is more streamlined. Ribbon is not always the answer Microsoft.
Despite these Ribbon changes the usage will stay the same, people stay with what they know. The copy and paste on the right click is something engrained in every application MS make. Let alone ctrl+c and ctrl+v which are completely ubiquitous in almost every application ever written.
Though, I'd just be happy with the location path bar and the file list... but I suspect I'm not alone in that wish, nor the typical user. Though I do kind of wish MS would make an expert user mode, and the nubbins mode for everyone else.
I mean, you could advocate Ubuntu here but they did just seamlessly blend in the most horrific parts of OSX in by default.
