So im running windows 7 on my desktop and the release of 8.1 made me wonder if its time to upgrade. i can get it for free from my university, the decision is simply about usability for me. so i was hoping some windows 8 users could answer me some questions.

do i need to use thew metro interface for anything at all if i install classic shell?

is there any win 7 feature that you are missing?

have you had any compatibility issues with games?

would you say that there is a reason to upgrade if you are not using a laptop/tablet and are not going to use the metro interface?
