I have had no billing problems, no major install nightmares, and am pleased with quality and quantity of the programs.
I would suggest once again that the CES show in about a week will "benchmark" their progress toward a DVR and other needed progress.
It sounds like I am relying on one show to base decisions on, but in fact if you take the shows of the last year and a half you can track trends.
Look at where they were, where they are, and you can project where they will be.
I know there is a good story of "where they were" because they have made some advancement in the last 18 months. You need to look at those accomplishments to build faith that they will continue to get better.
