I have friends that are die hard Tivo users. Tablo presented a much much much better return on the dollar... But I can't say "much much much" anymore... that's all. Price isn't going to be much of a factor anymore.
I do still like my Tablo, it's still a reasonable choice, especially if you don't need surround sound, popular show commercial skipping, native quality, etc.
So... what to do? Well, some here (and @TabloTV) have mentioned the strengths of Tablo. I'd really focus on exploiting the strengths more feature wise.... just saying... there's a lot of room for improvement, but can't say what can be done easily. No napping!
