The world's first Ubuntu phone goes on sale next week in an attempt to carve out a place for the Linux-based OS in the mobile space. Canonical said the limited launch is aimed at "avoiding the pain faced by other platforms" that tried to push their handsets to the mass-market too early, and they must work hard to get the Ubuntu Phone noticed. It will also be giving handsets to a select group of "enthusiastic Ubuntu and bq users" in London today.
