Let the hive mind of Engadget get that for you.
"I'm looking for a pair of quality headphones that aren't seemingly made of glass. I'm an avid BMXer which causes me to frequently bash on any type of technology that joins me for my daily riding. I've been through the higher quality headsets in the Skullcandy line as these are supposed to be built for "abuse," which is laughable. I cant wear earbuds or canal buds, as my large ears seem to have a repelling property upon anything that sits in them. Wired or Bluetooth doesn't really matter, but I need something that can hold up to taking a few hits every now and again. I'm trying to keep 'em under $150. Thanks!"
#3 - The Spring Update enabled upconverting to 720p and 1080i. I don't see any reason why the Fall Update wouldn't allow upconverting without the HD-DVD addon.
These same restrictions apply to the PS3 though, right? The $500 version has no HDMI and the $600 doesn't come with HDMI cables.
