It's called phased obsolescence. Isn't it really the exact opposite? If you have the last-generation iPod or iPhone there's really no good reason to go upgrade. It extends the life of your current device indirectly. With the 3GS being free with contract you can bet it will be very popular which means developers will have to take some extra time to make sure their apps worth with a 2+ year old device. (which also means they will have to work well with older iPod Touches) Apple is upgrading all the iOS devices to iOS5 except for the original iPhone 2G, 3G and the first generation iPod Touch. So probably about 200 million or more users are getting some significant software updates in a week or so.
