If "Free as a beer" OS doesn't perform as you expect it to perform, it makes sense to spend some money on something that does. Besides, with open source OS's that available today, s.a. Ubuntu, Fedora, etc. you don't pay for it, but support, that is if you are not pro, will cost you an arm and a leg. Of course, you can post on a support blog, but not always will get an answer you need.(Personal Experience with Ubuntu) Paid support will get it to you. So here's dilemma - Free OS with paid support, or free support with Paid OS. And remember, "There's no such thing as a FREE lunch".
