Let the hive mind of Engadget get that for you.
"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!"
the xperia is expensive; hope it does come out with a carrier soon at a subsidize price. i was at the mall here in vegas and a cellphone kiosk that sells unlocked phones has the xperia on display. *drooling with hope!
