After Erik, here's Ashley, currently Director, BBC Future Media & Technology, but moving on:
So, there you have it. I've enjoyed using Ubuntu, it has a simplicity and elegance that I like and some great features that other OSes don't have (and I appreciate that I've only been scratching the surface). And it's free.
But I'd say it's horses for courses. For enterprise-side usage, or as a developers' workstation, or as a cheap platform for people with a fair amount of time on their hands and a willingness to deal with all the websites that only vaguely support Linux, fine.
For me, as a day to day operating system, would I churn from Windows or MacOS for it? Not yet; perhaps in a year or two. Critically though, I think the BBC can, and should, do more to support the Free and Open Source community, and I hope this has at least shown my commitment to listen and learn!
