I thought I'd use a start button, but I made the decision to try and use the Windows 8 way for a while. If I'm going to despise it, I want to fully, truly have complete justification to hate it. That is, to have used it for long enough.
I did use it. I got used to it. I don't particularly love it and I think the option to use the start button as an alternative to the start screen and the corners would be great. I don't like that MS stripped them out as a FU to people who just want to go the old way. And I don't think forcing Metro apps to run in full screen or even bi-screen is the correct way to compel users to use them on traditional platforms. I think if we could run apps in windows alongside our regular applications, you'd see a huge uptick in users going to the Windows App store and buying apps.
I think they are leaving money on the table by making it an either/or proposition.
I also don't understand why MS thought the Metro UI should replace the start menu instead of the desktop. I mean, I can perfectly imagine how that would go. They'd have the Metro tiles on your desktop behind your applications. You have a taskbar like every other OS has always visible with time and power/signal integrity, but it'd be on the bottom. If it detects touch and a certain size, it adjusts the size of the bar to allow easier touch for whatever device it's on. You have a desktop button (or swipe) to go back to the default of Metro on your background. Start menu works same as always.
That'd be a perfectly blended, perfectly merged Windows and Metro UI. Instead, they seem to have just designed Windows 8 into this confrontational either/or Sophie's choice crapshoot instead. That's nonsense to me. Maybe with Sinofsky gone we'll see them go back on this stupid design and properly blend the two UI's.
But I use the corner with the start screen like MS intended. I did recently find the Windows 8 Start Screen Customizer (free) to make the Metro screen mostly-transparent over top my desktop, which mitigates a lot of the horror of a whole screen plastering itself over my desktop. But no, no start button.
Once I figured out closing apps was basically going to the left side, then right clicking on the apps shown and hitting close (instead of the god awful drag and toss via mouse), I was pretty much okay.
