I'm running RH 8.0 on one of my computers. It was a Windows 2000 machine before a win32 PE virus burrowed into the firmware on one of the cards in the machine. Once that happened, the virus would re-appear even after low level format of the hard disk, zero of the CMOS memory and re-flash of the motherboard BIOS. Very irritating. I put RH 8.0 on the machine so it wouldn't be a total loss.
The RH 8.0 is less likely to get nailed by a Windows virus floating around. It also gives me a UNIX like OS to host stuff like CVS. My python code runs portably between Windows 2000 and Linux, so it is fine either way. The loss of support for RH 8.0 will probably cause me to migrate the box to be a dedicated QNX 6.2.1 development system. I won't miss the goofy Ximian e-mail reader. It is damn irritating when I'm trying to clear the daily spew of SPAM.
Sounds like you have some experience with QNX. I tried it and found that it ran slower - even slower than Windows.
