So, for an investment of $50 you get to use best portable MP3 player with the best OS

You get to do that without spending that $50, but you do have to invest in Mac OS X.

or

But you didn't mention anything about Linux/FreeBSD/BeOS. On what did you spend $50 to get that to work?

or

Does it also enhance the iPod, making you need to reboot it once a day or crash?



Feel free to make up your own joke.
