"What we got in the alpha version of Ubuntu 11.10 was an
operating system that booted up much faster, allowed for snappier
switching between applications and tasks, and an operating system
that, overall, feels faster.
"While we tend to hesitate to review even beta software, let
alone alpha, we were curious about the work going on behind the
scenes; Mark Shuttleworth, the leader of Canonical, which oversees
Ubuntu development, went on record earlier this year saying the
goal is to have 200 million users of Ubuntu worldwide by 2015. That
would be a lofty goal for software that, of late, was considered
clunky and slow by some."
