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!"
i hope they would offer the download service on the ps3 also, it makes more sense on ps3, since the ps3 has a bluray drive. also if they can get better audio support in downloads the ps3 is the only system that can do hd audio. the xbox is limited in tha area.
while downloads will not be able to compete with bluray in terms of sales or qualiy, it would be good to have an an extra feature. plus you can download 3-4 blu ray/and dvds at a time and have access to over 7000 SD downloads ad soon some "HD" downloads via netflix (not the same quality of hd, since hd downloads arent nearly that good at all, but are better than standard def in most cases.
