A great backup solution for those with a TB RAID would be for Sony to make a 400 Disc BD-RW changer with double-sided capability. Imagine 400 discs each holding 100 GB of data = 40 TB of backup space. No excuse for not backing up every day.

I realize that the cost for 400 discs is alot now, but you could start small, maybe 10-20 to backup the 1-2 TB RAID. Then you have tons of room for expansion, complete data portability, corruption protection, and low power consumption all while having 100% availability.

This would be great for those with the new TiVo S3, too. You could go on vacation for a year or two and still catch all your shows. :)

The biggest benefit I am looking forward to is to allow your real nieghborhood to become a "network neighborhood" with no ISP's involved.

Use this with a propeller hat to recharge the battery.

After reading my theory again, I forgot to mention something. I know the commercial skipping is a big reason for time savings, but I assumed savings before that. Here's why. I generally save more time because I don't have to wait an hour waiting for my show that I do from skipping commercials. I use to still sit and flip through channels but with my TiVo I can watch something from yesterday while I wait. I still watch the same amount of TV per day and my theory is that most other people do, too.

I'm not sure the study proves your point at all. The study compares DVR'd homes to non-DVR'd homes. It does NOT compare DVR'd to pre-DVR'd. There is a big difference and there is more to consider besides just having or not having.

Everyone has a fixed amount of time that they devote to TV watching. I think that the same people who buy a DVR are the SAME people who watched 23 percent less TV to begin with. If you have less time for liesure activities to begin with, buying a DVR mean you can watch all of your shows instead of just 77 percent of them. Add to that the commercial skipping, and a person crunched for time can now keep up with the news that they've been missing.

Just a theory. I'd be interested in hearing what you think.

thanks for the spoiler, marty
