connecting their computer to a tv through USB to HDMI? I stumbled across the Atlona USB to HDMI connector at Costco. I was thinking about getting the mini or macbook and connecting it to my HUGE widescreen TV. It says "Resolutions supported up to UXGA 1600x1200 or 720p" Would the display be better since it's being connected to the HDMI? Anyone every try these or similar item? Thanks.
