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 real hand to the face is the price. There is no reason HD DVD media and hardware won't eventually drop to the current DVD prices. Plus you will eventually get a DL 30GB disc. While Blu-ray will never be able to be able to approach that cost due to license fees and production cost. (thank you Sony and it's supporters!!) 50GB would be great for backups and such, but I don't think it will ever justify the price premium. (as everyone has been able to see, Blu-ray's more advanced technology doesn't translate to better looking movies)
"but I don't think it will ever justify the price premium"
LOL
Blu-ray is cheaper per GB than hd dvd... and have more future proof variants in the face of BD 100 and BD 200...
