OSNews, Generic OSes Once upon a time, operating systems used to matter a lot; they defined what a computer could and couldn't do... Today, there's only one operating system: Unix (okay, there are two, but we'll get to that). This is why I contend that the OS doesn't matter - or that we need to take another look at the word's content, at what we mean when we say 'Operating System'.

The author claims that the only exception to the rule that there is only one OS (and that's UNIX), is Windows. It may be the only major OS that is more than subsisting but there are more OSs that used to be big that aren't anymore.

BeOS (and its open-source counterpart, Haiku) is much better than UNIX ever will be. Sadly, since it was built on GCC and other UNIX-like infrastructure, it doesn't cut the umbilical cord enough.

AmigaOS and MorphOS (and the open-source counterpart AROS) are both pretty fast and light compared to UNIX due to their custom kernals, but unfortunately, as time goes on, they need to run more Linux code and less native code and are succumbing to the peer pressure.

Singularity was designed to be different. But according to their article in the Communications of the ACM, they are going to try to integrate those features into the existing OS over time. Look forward to Windows 8 or 9 when they finally ditch hardware-based memory management techniques and adopt software-based ones that have finer granularity and can be optimized away at the compiler level when not needed. Oh well, at least they put some of their research money to work instead of feeding only hype like most of their bosses do. Sadly, this software may only see the server by the time it comes out.
