I have it installed on several old laptops/Chromebooks. It's cute, but it's not really performing how it bragged it would... Gonna have to find something leaner....
Never seriously... I only experimented with it in a VM. I know it's not against the GPL, but they way they rebrand existing things and then add licenses to them just feels scummy to me...
I mean, under the hood it's just Ubuntu. No one's questioning how reliable it is. It's just that everything that actually makes it Zorin is just a bunch of fancy skins. It was designed to be something you could load on your Grandma's PC and still have it look like Windows.
I work in a computer shop and we put Zorin on machines for some instances, like if it's a old/low performance machine or if the customer is trying to stick to a strict budget. We haven't had any come back, and people seem to like it.
