I'm all for supporting Devs that are pre/repackaging Ubuntu with a selection of applications installed and semi-configured for ease of use. And $48 for the "Pro" edition isn't that bad considering what you're really paying for is for them to package a bunch of software in an Ubuntu/Debian distro and then put a pretty GUI on it that looks more familiar to you. However, it's still Linux under the hood which is subject to all of the Linux quirks. And all of that is free to grab for yourself and add to a Ubuntu/Debian distro if you want to spend the time doing it as ChristopherChiesa described.
But I get it. It's why I pay someone to change the oil in my car at a service shop. Why, because the $50 I'd save in cost by doing it myself isn't worth my time and labor. For $50 more I don't have to crawl under my car and get my hands dirty. Peachy Keen. :)
