Hiya! I've had the idea floating around in my head for a couple days of somehow getting my town's K-12 public school district to at least try FOSS and see how they like it, and I'm leaning more towards Edubuntu for the workstations, but still, which would be the better distro for the workstations in that kind of environment? Edubuntu or Linux Mint?
It's a little bit unclear to me what exactly K-12 is (I know K9 ), but from doing an Internet search I guess at least in the USA this is denoting the last year of middle school? Like 18 year olds? I'm not exactly sure how that age group would benefit from Edubuntu. I've always assumed Edubuntu to be aimed at lower age group.
Edubuntu is using Unity. I'd go with Cinnamon instead, but that is a personal preference. Like you shared, you can install the Edubuntu packages on any Ubuntu based distro easily anyway. If you have to install to multiple computers, you'd probably want to look into Remastersys to clone one installation to all other computers. Or into creating a custom Linux Mint ISO with the Edubuntu packages installed: http://community.linuxmint.com/tutorial/view/918.
