iPoding has become a national past time, and iPod users are finding new, and rather remarkable, ways to extend the functionality of their beloved MP3 player of choice. Several Web sites featuring tips, tricks, and software have sprouted up, including iPoding.com and iPodHacks.com. You can also find iPod merchandise at everythingipod.com, including "everything" from car adapters and cases to headphones and FireWire accessories.

And we bet you didn't know that you could actually use an iPod to boot up your Mac. It can make a great emergency boot-up disk; when you put your iPod in FireWire hard disk mode, just install a Mac system and your diagnostic software of choice on the iPod. So when your Mac starts to act up, you can boot from your iPod to run your repair software.
