Have these people never purchased a new and improved product in any form? Ever buy a microwave over a toaster? Should a person who bought a black and white TV years ago get their money back because HDTVs are available? Should Ford give cash back to F-150 owners when the 2008 edition comes along? How about that casual PC user who is still using Windows 95? Should Microsoft issue them a rebate for every version of Windows released afterwards?
