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 hate the branding here, it's lame. Sony's SXRD is basically a branding of the same basic technology that JVC calls D-ILA. The basic technology is known as LCoS, liquid crystal on silicon, a specific variation of LCD.
I think there are several 4k projectors out there. I'm surprised that JVC doesn't have one for sale already. I could have sworn that they put together the projector for NHK's UHDTV demo theater, which is 7,680 × 4,320, 4k should be simple in comparison.
