I have to disagree. The comparison you make is unfair. I experienced QNX and Beos too. But what could you really do with it out of the box, compared to a full blown Linux-distro?
The 'feeling' of snappiness is a matter of carefully choosen defaults IMO. Almost nobody does that anymore. So have this lowest common denominator, and mostly crappy tools to change them from within the GUI, or have to dive down in the cesspool of myriads of different config files in different formats and places, and in addition an explosion of complexity of subtle interactions of several subsystems. Regarding the shitty hardware... The f-ing fastest desktop experience i ever had was somewhere in the late days of KDE 3, across NetBSD, ArchLinux and Gentoo, on Pentium3@933Mhz with 512MB RAM, onboard I815 Intel graphics(edit: with the 'superspecial' 4MB VRAM Dimm-thingy), and some IBM Deathstars.
With the same toned down look across all three systems, and toolkits, instead of the usual teletubbyfication. What can i say? When your KDE 3 crashed you were holding it wrong, or it was somehow miscompiled, be it the optimization , or some libraries. For me it was rock solid and lightingly fast, at least in my configurations. The same can be seen nowadays with systemd and pulseaudio.
They can be used if configured right. The question is if one wants to be hassled with that, if it isn't. /endrant |
[EDIT] oh as for BeOS, it ran a lot of the same junk I ran on Linux just fine. Better, really. It wasn't suitable for a server, but that didn't and doesn't really matter for one's desktop OS experience. Especially these days—can it run a VM (as one supposes any modern BeOS-alike could, because why not)? Cool, then I can run most any deployment target I like on it.
