Like some of the other Ubuntu releases, Lucid Lynx is LTS or “Long Term Support” meaning that the desktop version will be supported for three years and the server version for five years. This version also comes with a netbook version, with improved boot-up time.
Now to the stuff i want to talk about, The desktop in this Ubuntu version is social even from the first boot-up in the form of a built in integration in the panels Memenu, with Twitter, Identi.ca, Facebook and other social networks. A new design with cleaner boot-up, a new area for messages and a new desktop background should, according too the developers, give the distro a new fancy look, there’s also a new theme with new icons.
