Well, let's recap. The TiVo people have been promising for some time they'd release a new model of TiVo that would handle HD signals from a DirecTV satellite, which is what I got. They promised and they promised and after so many delays, no one took them seriously. When they recently promised it by the end of 2011, no one believed it would happen…but they made it, almost. The THR22 is not out in the sense that you can actually get your claws on one but you can place an order with delivery promised in January.
Whether you'd want to or not is another question. Many features we've seen on recent non-satellite TiVos are absent, including several that seem like deal-killers to me. This comparison chart from the folks at WeaKnees (a great place to buy TiVos or get yours repaired) shows what it does and what it doesn't do. I won't be ordering one and given how long it will likely be before another model emerges, I'm seriously considering a switchover from DirecTV to Time-Warner Cable. This is not a decision to be made lightly but that's how I'm leaning at the moment.
