Linspire and one of its biggest desktop Linux rivals, Ubuntu, are talking about collaborating to offer Linspire’s CNR (Click-N-Run) application download service to Ubuntu users. CNR is a subscription service ($20 annually) through which users can install thousands of software programs with ‘literally’ one click, CEO Kevin Carmony said. Ubuntu, according to DistroWatch.com the no. 1 most popular Linux distribution (as ascertained by number of clicks), has nothing like CNR available for its users. Both Linspire and Ubuntu are based on the Debian kernel.
