Pure Digital today announces a simpler solution: a camcorder that plugs into PCs and has built-in software to transfer and process the video with one click. It's a new edition of a camcorder Pure Digital first began selling in May. Two units -- $129 for one that holds 30 minutes of video clips and $169 for a 60-minute version -- are now being shipped to stores. They feature one-click uploads to Google Video and Sony's Grouper video-sharing service.
