There is no subscription model with Ubuntu: all updates are completely free to everybody, paying or not, from the same source. Canonical sell value-added services (technical support to end-users, hardware certification and custom engineering to manufacturers, etc), but there is essentially no per-seat charge for using Ubuntu[1]. You get the best of both commercial and community distros: third-party certification and corporate commitment from the backer, at zero cost. [1]: Except, possibly, for technical support, which is sold off-the-shelf on a per-seat basis. But it is completely optional. -- Etienne Goyer 0x3106BCC2 "For Bruce Schneier, SHA-1 is merely a compression algorithm." http://geekz.co.uk/schneierfacts/fact/164
