Tux Machines (TM)-specific
These days, if a desktop-focussed Linux distribution wants to stand out from the pack of Ubuntu-wannabes it either needs to be especially slick or offer something a little bit different to the norm. Peppermint Ice falls into the latter category: It's a Debian-derived (via Ubuntu), lightweight Linux distro that's designed for netbooks and has a strong focus on Web applications.
Peppermint Ice's main claim to fame is its use of a 'site-specific browser' (SSB), dubbed Ice, which is based on Google's Chromium browser. Peppermint One, a fraternal distro from the same developers, uses Mozilla's Prism (a project that, according Mozilla Labs' projects page, is now not being actively developed). An SSB is a stripped-down browser that lets Web-based applications and services be treated in a somewhat similar fashion to a standard application: instead of navigating to a site using your browser, you can simply click on an icon on your desktop/applications menu/taskbar and an independent browser session is launched for that application (with none of the usual toolbars and menus you find in a normal browser session).
