what do you think the chances are of us being able to play dvd's in say 20 years time.VHS lasted about 20-25 years,you can still play tapes now from then.The DVD format has been around for about 10 years now.But do any of us want to spend still 1000's of dollars to rebuy stuff that we had on VHS (STAR TREK anyone),in yet another format in even 10 years.Hell,just 5 years after the release of Star trek original,they are expecting us to buy it again on HD for $130 dollars a season.I don't know about you guys but I wanted to keep dvd's until I died (I'm 37),50 yrs?,yeah right.I think the next big thing for me is tv on demand via internet.
