I just installed Ubuntu 12.04 and plan to use it for the day to day stuff. I rely on CAD/CAM for a living and it's looking like so far even though there's a lot of great programing in Linux form, there isn't much out there in the CAM realm.

Am I correct on that? I don't like dual booting if I don't have to but if I have to I have to. I already have a number of music creation programs that I know don't exist in Linux form. But CAD/CAM are more regular use.
