tiVo literally doesn’t have a model that works for me right now, which is kind of scary. I don’t have cable, and I’m certainly not buying a DVR with only two tuners and a tiny hard drive. I can’t believe they canceled their four tunerThe Edge has two versions including the Tivo Edge for OTA (over the air). They are pushing it onto Roamio owners because the Roamio was sold with the guide included for free for life. They want you to change to the Edge OTA which charges $6.99 PER MONTH (only that cheap if you pay by the year). They made a mistake income-wize with the Roamio, and now they are trying to correct it by pushing you to switch to the Edge.
