Tried BeOS last year (one of these yellow-tab/Zeta-thingies),and can only
say,what a POS ........
1) It didn't install on the laptop,cos some smart-assume opted for
1024x768 on the installer. Connected my 18" TFT to the VGA-out, installed
changed the res (kinda hard to find), looking good and on the internal
screen. Rebooted, had 800x600, but only on the vga-connector......
2) There was some stupid "tip-of-the-day" crap,but it had no obvious way to
shut it up like the ones found in KDEor even Win98.
3) Doing that by hand affected lots of other apps...
The best PC-OS I ever came across (not counting Amithlon ;-) ) was QNX,
but that has even less "user-SW" than AOS....
