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!"
And just for clarification, it isn't only about Hi-Res Video Support. It's about drivers that use the chipset video support properly. That include a whole lot of things, and would change the performance of everything related to graphics (pretty much everything) on the phone. Hi-res video is being highlighted because is a much more noticeable issue, but there are a lot of examples at www.htcclassaction.org.
