For the past eight years, a CableCARD and a TiVo DVR have gone hand in hand. No more! Within the next few weeks, the limited edition TiVo Roamio OTA DVR will be available from select Best Buy stores for an initial price of $49 (plus $15/month service with a one-year commitment). That's $150 cheaper than the existing base model TiVo Roamio, and still boasts the four tuners, 500GB of storage, integrated WiFi and almost the same software and accessories (TiVo Stream, though it doesn't support TiVo Mini). The main missing features, for a fourth of the price, are a CableCARD slot and whole-home capabilities. This means you'll need an antenna and (ideally) to live somewhere with decent over-the-air reception. It's an especially interesting offering for those looking to cut the cable/satellite cord, while keeping access to new shows from the big networks. TiVo might not be kidding about this being a limited edition either: The company is clear in pledging its allegiance to its cable TV customers while at the same time attempting to appeal to those not interested in paying more than 20 bucks for a monthly TV subscription. So, depending on the reception from customers and partners, we could see TiVo axing the Roamio OTA if things don't work out.
