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!"
its tempting to get one. i love the black and white bodies and also the GPS feature. I'd also love to up my 4gig iphone to a 16 gig, but for $10 more a month and take away my text?! no way i will switch until they released a reasonably priced, contract free unit.
