So, as Windows 10 started rolling out yesterday and I already have it installed, I thought maybe we could talk about it a little bit and I'd answer your questions as well.
First off, the desktop mode is extremely similar to Windows 7, apart from the design. Everything is where it's always been, you've got the power button back in the old position inside the start menu. I see absolutely no reason why you wouldn't upgrade from 7 to 10.
And I see little reason to not upgrade from 8 to 10 as well, but maybe you should wait for a bit, as it is currently not possible to install new apps from the store due to server overloads and you can't seem to keep your apps when upgrading. The missing charms bar has been replaced by the notification center, which has more functionality and can be accessed the same way on touch devices, which was one of my biggest concerns with the Technical Preview.
The only two things I noticed negatively in terms of UI are these two: Firstly, the taskbar isn't hidden in tablet mode anymore. It is now always present and contains the start, back, search and task switch buttons in addition to the clock and a few system notification icons. This might be good, but I was concerned about full-screen video playback when I first saw it. Luckily, apps have the ability to offer a full-screen mode button which works in desktop mode as well, so that was a pleasant surprise.
The second thing is the way brightness settings are now handled. In windows 8, you could start dragging on the brightness icon to open a slider. Now you have a similar setup to windows phone, where you can only click/tap the icon to change the brightness in increments of 25%. But 0% are missing here. So when you don't have a keyboard connected to your convertible, you can't set the brightness to the lowest setting without opening the system settings. I guess that will be fixed later down the line, though.
That's it for my personal impression. If you've got any questions, ask! I'll gladly try to find an answer.
