No, I just think you're wrong.
You really think most would boycott it? You know how internet boycotts work. People complain a lot and say they are going to boycott it, and then buy it anyways.
So even though what was formerly known as Metro is stupid for a desktop, most people here will still probably end up getting Windows 8, even if they don't like the start screen.
I've heard people around the office say EXACTLY that. "I have no desire to update because it's really designed just for tablets/phones." I ask where they heard that and 99% of the time the answer is 'the internet'.
I hear people complain, but I also never hear anything that's a valid reason. No start button? So what? The only thing missing from the start button you can't get by right clicking the lower left corner is the All Programs list. That's now just the Start Screen. Not really a hindrance to working on the desktop. That, and no gadgets are about all that changes from the desktop experience. If something didn't work or was much more difficult to do, that might be one thing.
Like with Vista, they've come out ahead of the game and said it's a big change. From a desktop standpoint, I don't honestly see that big of a change. Just all programs to start screen really.
I'll admit, I didn't like a lot of what I saw in the customer preview. What bothered me most was it was missing little things that would make life much easier for desktop users - no scroll bar on the start screen, no indication you're supposed to click the corners of the screen to access stuff, or the right side of the screen for charms. Power off was buried 3-4 levels deep in the charms bar. Closing apps wasn't explained anywhere. There was no clock on the start screen.
All of that was address for RTM - except clock on the start screen and how to close apps, but someone has made an app for that. Though i find it immensely ironic that every win8 phone ad/article i've seen has a photo with a live tile clock at the top of the screen. I've since figured out how to close apps, but while that's nice to know now - on the desktop I realize i won't ever use any most likely.
I'm interested to see, to be honest, how it functions on a tablet. I think sharing desktops, programs, and apps between desktop and tablet could be quite cool. We've only seen half the show so far. I think how it all ties together is a big part of the plan, but we've not been able to see that yet.
