Good stuff - as Mac hardware is apparently what Linus Torvalds uses, then I suppose it must be good enough for most other Linux users as well!
I know nothing about video editing, I have never shot a video in my life (I hardly ever take pictures never mind video), but if that is what you are looking for, have a look at this site:http://www.cyberciti.biz/faq/top5-linux ... -software/
especially the comments afterwards (you have to ignore the people slagging each others opinions off, but you should get some good ideas from there). As someone who knows nothing about it, OpenShot sounds like a good bet - available through the package manager as well.
