"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 have to say Blackberry is one of the best phones I have ever had, and believe me I buy everything that comes out in the market.
