But sometimes it's not a bad thing to remember that doing it yourself -- whether you're concocting a satellite dish or a Linux system -- can offer a level of customization that can't be found in products built for general use (not to mention it's usually a lot less expensive). A manually-built item not only gives you exactly what you want, but it helps you learn what makes that particular technology tick. And there's no denying the sense of satisfaction that you get from creating something that is as good, or better, than one that is commercially manufactured.
Of course, "making your own" can sometimes be interpreted in ways that are not as productive. For example, there is an ongoing battle these days between students and other computer users who want to make their own video and audio playlists without any interference (even when it involves copyrighted material), and companies such as the Recording Industry Association of America (RIAA), which wants to prevent that particular type of creativity, even when it's on an individual scale. Stay tuned for further developments.
