We can pay $$$ for some software.
We can pay $0 for free software.
And now we can pay $150 for no software -- a brilliant idea from Sony. ($50 to not install trialware software on your new computer, on top of a required $100 fee for a "business" verison of Vista. Sony has since recinded the fee.)
Perhaps others, those who like pushing software upgrades onto our computers, such as Microsoft and Apple, will start charging us if we say "No!" to potentially-damaging upgrades.
(Reminds me of pay parking: being charged to not use my car.)
