I don't know about the devs at MS, but I got used to it pretty quickly. My new laptop came with Win8 -- which I committed to using for 2 weeks before I spent money on a Win7 license. At first I hated the stock interface, but I got over it. The desktop is a desktop -- I can still load software off the task bar by pinning a link there. The only time I see metro is when I need to load something other than the core 4-6 tools I use (Firefox, Word, Excel, IE and Publisher) ... so mostly when I want to run steam or wow.
For everything else, just hit start and start typing what you're looking for -- it pops up.
Now -- I don't think it's "better" than the start button (which did all of that without a full-screen interface that blocks my view of open docs, etc) but it's not all that bad.
The trade off is that the rest of the OS makes a bit more sense -- the interface is cleaner (less clutter around the window edge), file and print sharing is more stream-lined, etc. I have no idea what the charm bar is for, I think it should go away. But overall -- it's a standard windows experience - slightly annoying but it gets the job done. I have to go back and forth from Win7 (at work and on my desktop at home) and Win8 on my laptop -- not really enough of a difference to notice 9 times out of 10.
