dumbmoney,That's true today, but if the bit cost of hard drives continues on the present trend, very soon (3-5 years) it will be cheaper to store video on a hard drive than the equilevent stack of analog tapes. And of course you'll be able to keep a nice size DVD collection on your hard drive as well (the studios are gonna hate that). I'm not sure that's going to be true anytime soon. You can store a 2-hour movie on a tape that you can buy for $4. Since that equates to the equivalent storage of a DVD (roughly 5G to use a round number), you're looking at about $1 per Gig. The cheapest I've seen drives lately is about $99 for 8G (Fry's Electronics) or the equivalent of $12 per Gig. If the price per Gig continues to halve every 18-24 months (my last HDD purchase was an 8G drive for $179 about 2 years ago), then we'll hit the $1 per Gig point in 6-7 years. And even then granularity will be an issue, since the fixed costs mean that you won't actually be able to buy an 8G drive for $8. You'll get a 100G drive for $100. And besides tapes, recordable DVD disks will probably hit the under $1 per Gig price pretty quickly. Then there's the convenience factor. I think it's much more convenient to keep a movie on a tape or DVD disk that I don't have to worry about dropping (especially with 4 small children). From the way the Disney tapes get tossed around and then still run, I'm convinced that Disney must put their tapes through Tempest testing. And from a granularity point of view, I can lend a friend a single movie on a DVD (I wouldn't want to loan him a $100 100G drive). On the other hand, it would be nice to be able to load up a hard drive with a dozen movies and pop it into a slot on the dashboard of the car to let the kids watch movies on a long trip rather than deal with a stack of DVDs or tapes. So, having rambled about all that, I would agree that there will probably be a mix of technologies. I like the Tivo idea for the quick and dirty, pause-the-show-while-I-answer-the-phone, record-my-favorite-television-shows-while-I'm-on-vacation types of uses. I think they'll be very successful, and that should translate into additional products that use hard drives in the AV world. Dave
