I plan to post on my experience of using Ubuntu as a primary OS and in the interests of disclosure should explain that I now work for Canonical, the lead sponsor of Ubuntu
For the last nine months I have been working with Jane, Mark, Matt and the team building Canonical's business development infrastructure to promote the Ubuntu project. It is period that has been extraordinarily exciting and enlightening. The smarts, humour and energy of everyone in the Ubuntu project are only outweighed by the incredible sense of community, common purpose and an unwavering desire to improve Ubuntu and FLOSS in general. It is truly an honour to work with this community and this project.
As for the results of the work - www.ubuntu.com and www.canonical.com will continue to be the best source of information.
