Let the hive mind of Engadget get that for you.
"I'm looking for a pair of quality headphones that aren't seemingly made of glass. I'm an avid BMXer which causes me to frequently bash on any type of technology that joins me for my daily riding. I've been through the higher quality headsets in the Skullcandy line as these are supposed to be built for "abuse," which is laughable. I cant wear earbuds or canal buds, as my large ears seem to have a repelling property upon anything that sits in them. Wired or Bluetooth doesn't really matter, but I need something that can hold up to taking a few hits every now and again. I'm trying to keep 'em under $150. Thanks!"
I can plug my iPod into as many computers as i want and add whatever songs from that library i feel like (minus DRM'd songs of course).
It's called "manually manage"
If we were talking specifically about auto-syncing, then maybe you have a point, but considering that "Manually Manage" is an out-of-the-box option (no hacks or 3rd parties involved) that will allow you to hook up to whatever library you want and dump songs onto your iPod, i'm going to re-redirect my "wtf" back to where it belongs.
