Peppermint OS One
Peppermint OS One is a web-centric Ubuntu remaster that passes up common desktop applications like OpenOffice.org in favor of web-based alternatives such as Google Docs. And it doesn’t stop with office applications either; Peppermint OS One integrates video sites like YouTube and Hulu right into the desktop experience.
LXDE and Prism
Peppermint OS One uses LXDE for its desktop environment. This means that it’s very fast and should work well even on machines with limited CPU and graphics horsepower. Since it makes great use of the cloud, you’ll definitely need to have a network connection available to get the most out of Peppermint OS.
