I installed Jolicloud a little while ago to an 8GB stick and have dipped in and out of it on a fairly regular basis. And now it's getting more use than Mint.
And all it took was some updates.
The first one to catch my eye was the appearance of Spotify, the music streaming service. Jolicloud had obtained invitations for the free version, supported by ads, for Jolicloud users and a one click install was added to the applications tab on the dashboard. It's not a native version, it runs under Wine, but it's still a step in the right direction. Purists may disagree. New users will be happy.
The other update introduced the Google Chrome browser with Flash already added. Yes, it's still nowhere near ready, but I've had no problems while writing this entry and I can watch flash video (YouTube, BBC iPlayer and Channel 4's 4OD service) in full screen with none of the choppiness that seems to blight a great many other distros at the moment. It starts almost instantly and it kicks FireFox's arse in the speed department.
I keep reading forum posts that say Jolicloud is just Ubuntu NBR with codecs, netbook drivers, Prism etc. added.
I say Jolicloud is greater than the sum of it's parts.
