We are awaiting delivery of our TiVo superboxes in 2010. (Knock on wood.) In the meantime, I use my HR10-250 for about 75% of series viewing (HD OTA.)
I hope that the HR2x faithful get the option of an HR superbox of their own in 2010 as well. You guys have earned it.
I'm not expecting much more than a little relief from software updates. And a replacement unit might be even worse. I'm waiting for the MPEG-4 TiVo to arrive in 2010, as are many others.
I hope Tivo calms those who are unhappy. I don't hate or love Tivo, but I feel bad because I know I'll laugh on the inside if Tivo has it's issues.
