If you stumble around on Amazon, you'll find that you can still purchase old Apple software that's well over a decade old. Take OS X 10.2 Jaguar, for example. Originally released in August of 2002, you can still purchase this bad boy for just $113.99 + $5.99 shipping nearly 12 years later!
Even more comical is that Amazon recommends you combine it with the original version of OS X for the low, low price of $142.94.
Of course, one's natural inclination upon seeing this is to ask, "Who the heck still needs this?!"
And sure, there are folks out there with old machines lying around that can't run more recent versions of OS X, but come on people, it's time to let go!
