"I've found myself using my PC for a lot of conversations lately, and I'm also considering recording a podcast to share with anyone who will listen. There are tons of USB headset / microphones out there, and I'm hoping someone has some solid recommendations based on experience. I'll consider both headsets and standalone mics, by the way, but I'd like to keep the bill under $100 if possible. Help!"
I play all my iTunes songs in my car via an iPod. Apple by far gives the consumer more choices what to do with the music they buy. You can always burn the tracks to a CD and take that in the car. Even though I have an iPod I usually remove the DRM from my iTunes songs anyway. That being said, it's only a matter of time before someone will crack a new DRM.
