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 laptops are pretty sweet. Whenever I get the need to upgrade my iBook I'll be getting one of those. As for now I'm planning to save up for a new Power Mac once those go to the Intel chips.
Personally I like the new power connector on those laptops. Very slick indeed.
