It wouldn't be so bad if all it took to reinstall was a nice stack of CDs and a little time. But then there are the upgrades that demand to see evidence of old installations (only some of these are benevolent enough to be able to see examine an old installation CD for evidence).

Then there are the online upgrades since you got the software. Bringing Win2000 up to snuff with all the security upgrades is almost a day in itself, and if you do it online, how open are you to attack while you're pulling in the defenses?

Then there are all the odd applications people accumulate. Do you have all the original disks? I have an application that I still have to load 11 floppies in to install!

Upgrading to a new OS also raises the issue of which old applications just aren't going to WORK any more, never mind drivers for old hardware.

I will upgrade eventually, but not until literally forced into it by one of my newer applications refusing to work any more with Win2000.
