This is mine at the moment. I like to keep it nice and clean. I think it might be because of the PTSD that I got from looking at my parents' laptop which has completely been overtaken by files on the desktop.
I couldn't comment on the cost, it was already implemented before I started.
It works pretty well for seeing and controlling multiple screens at once, and you can deploy some basic policies (although these are better handled through GPOs). I don't have much to compare it with though unfortunately.
Yes it is! I'm on a 10+ year old computer that can barely handle it, let alone try Windows 10. My dad and I are trying to get the new laptop I got replaced because it was faulty product. So I'm still with 7~
