Re: This sort of issue is not thought about
Have a look around.. You'll find many pros using Linux for their day-day stuff. Film making, picture editing, publishing.. Been some interesting threads on here in recent weeks...
As to small.. The most used kernel in the world by far is "small"? Windows has the desktop, Linux has servers, phones, tablets etc.. You know, the stuff people use today..
And didn't "multimedia" die out in the mid 90s? :)
