it's statements like that make linux users out to be complete asses.
i've got 2 XP boxs that have never been down ever. they are always on and never crash.
98 on the other hand........well we all know.
i love my two linux boxs(pclinuxos)but lines like that are just plain stupid.
You mentioned a total of four computers.
Try dealing with four hundred servers and thousands of users, then get back to me.
Keep in mind that uptime is not just a measure of how often it crashes but how often you have to restart it due to resource contention or general maintenance patches..
