I run NT Server on a Pentium with 32mb ram and about 40 swap spread out on
two drives and it runs fairly quickly. I've run 95 too on the same
machine, and things do run faster (cause 95 uses less ram) even with 32 mb
swap. Running 95 on a 486 with 20mb ram & 20mb swap, things were painfully
slow, but that was most probably due to the fact I was using a 486, no
major disk swapping.

I've only seen a "blue screen" once on NT, and that was when someone ran
WinNuke on me (nt dumping core.. what fun..), gnu-win32 has never brought
down my system.  Using alt-ctrl-del to close programs on Win95 has brought
major unstability to my system and sometimes rebooted the system, but make
itself hasn't done that to me.

LOL, Microsoft fixing bugs... man that's a good way to get a laugh.
