The expression "NO, I WILL NOT UPGRADE" is showing a disconnection from Redmond. "This hardware is fine, I will not switch to Vista, thank you".And from there, from that point of rebelion, other alternatives sounds plausible.
If you are feeling that Vista is a scam, and that someone is trying to push you to buy new hardware, when you are told that there is a FREE version of an OS that lets you stay with your hardware and is community based you hear bells from heaven.
