"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.

This seems sort of pointless to me. For one thing even if you have a product that can play both formats, you still have to actually have one or the other of the discs. Unless people go around buying two of every movie that comes out this is just overkill.
Oh and lets not forget the cheapest blu ray player will most likely be the playstation 3 upwards of $450-$550 (I really really don't think sony would try to sell it for more)
