Eh, the difference here is that IE isn't an OS, and people can use FireFox or whatever else and *gasp* still have a fully functioning computer, running just as fast as it always did.
Heck, even though MS did stop OS support for XP, they didn't cripple it to the point of it being unusable.
If Apple was in charge, they would release a OS for those computers that would make it run 1000% slower, make it impossible to use any other OS, and call it a day, and wait for people to buy new hardware to "fix it".
