Metro is "easily avoided" if you're already a power user - if you know enough to install a start-button replacement, and replacements for all the other Metro applications bundled in.
My job is serving as the one-man IT department for my employer. I installed a copy of Win8 on my work desktop to test it out, and very quickly came to the conclusion that there was no way I was going to inflict it on my users. Even if I had a BOFH-style hatred for every single one of my coworkers, self-preservation would dictate I'd want to avoid all the helpdesk calls that Win8 would generate.
In the months I've been using Win8, I've managed to get it tweaked to the point that the parts I hate mostly stay out of my way. But this isn't something I'm going to install on any computer I'll be expected to support.
I can't image what Microsoft was thinking expecting "tech savvy" people to serve as Win8 cheerleaders for their friends. Most "tech savvy" people hate Window 8. Like most IT guys, I also do a bit of moonlight on evenings and weekends, and I've gotten a lot of people asking for advice for a new computer. Without fail, I always point them toward Windows 7 machines. You might not find them sitting on the shelves at Best Buy or Walmart, but they are out there, and will be until either Microsoft ends support for Win7, or they abandon their stupid insistence on cramming a tablet interface on to a desktop.
