“Optimism apart, there are things that needs to be sorted out. I
have been using Ubuntu 11.04 for about a month now and some issues
have started to creep in. First and foremost, Unity desktop is not
anywhere near stable. There were more than 3 instances where Unity
will simply crash(without even a desktop freeze) and go into login
screen mode(like while you restart x). Stability is something Linux
is very famous for and the issue needs urgent attention.“Though many attributes of Unity is in tune with smaller
devices, it is not really a “light” OS in terms of performance.
Boot time remains pretty much the same(if it has not deteriorated a
bit) and memory usage is quite big too. Not the ideal
characteristics for an OS aimed at smaller screen devices if you
ask me.”
