"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 have to agree with you. Same thing happened with DVD-R(W) and DVD+R(W). Both formats were competing with each other, now both formats co-exist. Same thing can happen with high-def DVD's.
