Linux Mint is the distro you're looking for. Especially if you're looking to set it up for non technical users.

the only problem with linux mint is that you constantly have to reinstall it because there's no update mechanism

I have tried Mint, and there was a update mechanism - it was either Ubuntu's do-release-upgrade or something on top of that, I honestly can't remember. But the system didn't look like a normal installation after it, that's for sure. Fonts were a bit weird, some settings were migrated and some weren't, it didn't feel right.
