Let me make it clearer, then, I like the changes.
I don't avoid Metro, although I don't go into full screen Metro apps very often. I like the Start Screen because it gives me better organization possibilities than the Start Menu, and I have all of my gadget-type information at a glance when I start my computer. I can see the weather, news, emails. I also like the notification system, so I use Metro apps like the eBay app to bring me notifications.
As for my workflow, my workflow was not impacted at all by Metro. I learned to use pinning back in Windows 7.
