I agree on the charms bar. I thought that thing was brilliant and I am going to miss it a lot. I admit I have not used win10 in tablet mode, because my tablet is a Surface RT, so I can't thoroughly judge win10 yet. But the worst thing is definitely the mail, people, store, sports and several other apps which are a far inferior. Still waiting in hope for final versions.
Then again, bear in mind that I have a different opinion to most people on these things. I still like vista.
Yeah I can't use tho people calender mail apps on my PC for some reason, they are in some weird superposition where I can't open, install or remove them. And the sports one never bothered me anyway. The beauty about windows is that those apps can be fully replaced by third party ones. The new store app is fine in my eyes.
I liked vista as well, but it was full of unnecessary features and system-deep DRM integration that righteously bothered people. It didn't stand a chance against win7.
I was never a fan of Windows 8 with the very huge differences in UI between Metro and Windows. I feel strongly that a continuous user experience is important and Windows 8 was frustrating for me on larger screens (close by). I've not tried Windows 10 yet but what I've seen does look promising for me as a desktop user with a single large screen.
The only two large changes in UI are that the start screen doesn't have to be full-screen anymore, it can be resized to a start menu, and that the "Modern UI" apps can now run in windows as well. That's pretty much it. And suddenly, it became much more usable for everyone. I do agree that a lot of the changes made to windows 8 with 8.1 were absolutely vital for user experience, though. The initial version was hard to swallow.
Ok, they've got the new virtual desktops, but I don't have any incentive to use those, I have three screens already, and multi-monitor support with virtual desktops wasn't great in any OS I've ever used.
