Windows 10 is way better than 7 in my opinion. I like the Microsoft is attempting to be more fully featured with their ecosystem between edge, outlook email, and one drive and office.
That said, execution is not there yet. Edge needs to be more like Firefox or Chrome with ability to add extensions. I think edge is fine as my default pdf viewer, I haven't needed any other viewer yet. The said edge is way too limited as a browser.
Windows 10 has an email desktop app that integrates with www.outlook.com email address/Microsoft account which I use for my personal email, and the interface looked great and runs from desktop instead of opening a browser to get your email.
I haven't used any of the office 365 stuff, but the included 1TB of cloud data is a good deal packaged with the office suite. Google drive 1TB of storage is more than office 365. I use office 2010 and will keep using it until it loses compatibility.
On my laptop I had windows 7, updates and problems kept frustrating me so I installed Linux mint, and used that for about 2 years on my laptop, there were some hurdles setting up some things I needed, but I got the hang of it.
After 2 years of Linux, I needed a 3D modeling suite on my laptop that isn't available on Linux so I went and installed Windows 10 on my laptop. It runs great. The laptop I got around the beginning of 2011, so it is betweem 5 and 6 years old, core i3 11". I ugraded it to 8 GB ram and 256 GB SSD about a year ago.
The most annoying windows 10 feature maybe the updates, if that is an issue the get the Pro version so you can schedule the updates. Problem solved.
Windows 10 seems to be moving more toward the apple and chromebook model of coming with all of the basics and requiring fewer outside apps to be installed. Really I think Word and Excel should be included with windows, or at least windows pro, but they are too valuable.
