I'm just about to get a macbook. I'm wondering if there are "free as in free beer" applications just like on my ubuntu. Does it have equivalent software such as Open Office, Gimp, Camstudio, Any video converter and Audacity on a Mac. Also, is it easy to install ubuntu 10.04 on a new macbook? Is bootcamp pre-installed on my system? It's a 2.4 GHz core 2 duo with Geforce 320M.
