It's good news that Click has finally talked about open-source and more specifically about Ubuntu since the last few weeks.
A few years ago, Stephen Cole (remember that Click Online presenter?) said that he did not consider Linux to be an OS since it was not enough user-friendly and many hardware wouldn't work. But nowadays, all this has changed. Most linux distros have a superb GUI (Gnome and KDE, amongst others) and many devices like printers, scanners, webcams, ADSL modems, and others, have drivers in-built in the Linux distro.
And on top of all, open-source is everywhere today!
I'm using Ubuntu Server at work and Kubuntu Desktop at home. I should say that the server is really easy to install and deploy. Apt-get is really a nice thing (thanks Debian!): installing and upgrading packages are simply a pleasing thing.
