it's kind of sad how computing has moved towards monocultures. Even just 10 or 20 years ago, there was way more variety on operating systems, internet browsers, that kind of thing. That variety was good, it meant there were more ideas flowing around and more opportunities to develop new and interesting operating system designs. Now you basically have to choose Windows, Mac, or GNU Linux, or if you're really brave *BSD. Anything else and you will not be able to use your computer for everyday tasks
