After a month of using my two HR20s, I have to say I don't miss the HR10s. Sure, there are some muscle-memory moves that I am having to relearn, but overall, the new units are just as reliable as the old ones. My Harmony remotes work just fine, same basic config. My wife hardly noticed. And I was able to sell my HR10s for cash. Which means my upgrade actually earned me $200. What are you waiting for? When D10 lights up next month, there will be a rush to the exit and you don't want to be left behind. I loved Replay, moved on to TiVo. I loved TiVo, moved on to HR20. I love my HR20s, for now and until the next big thing appears. My money says you will, too. Move on, boys.
