Taking your comments at face value, then WinXP is the way for me to go - like many others here on TBN, I'm networked at home -- currently, 5 computers, although 2 are old ones about to be taken off line once I finish milking them dry.
My router, and most others, has a hardware firewall. I've been on the sites where they will (with your permission) poke into your connection and try to find vulnerabilities. The report is that my computers don't exist -- total stealth. You can't get past the firewall unless I open up something.
Viruses that can open ports can sneak in through email. I have Norton scan everything and I open nothing unless I know where it came from. Still, I have had the occasional virus sneak in through a web site -- Norton has caught them and quarantined them. These are vulnerabilities in the browser and the email handling program, not in the OS (although, for all intents and purposes, IE is part of XP, now). They can take over 98, also -- I had to junk one hard drive that had a virus hidden on the boot sector or some other outside track, where it couldn't be reformatted. It re-infected everything I put back on it.
WinXP is stable, and if a program does crash, you can usually recover without rebooting. 98 can't do that. That's enough for me. XP is based on NT/2000, and has the stability built-in and improved. 98 is lightweight in comparison. XP may be bigger (and thus "heavier" in your terms), but it's because it does more. I use both XP Home and XP Pro, and find them equally good. I wouldn't go back to 98 for love nor money. I've been using personal computers since 1979, made my living with them for many years, and am considered moderately knowledgeable.
