Let the hive mind of Engadget get that for you.
"I need help! I want a small pocket camcorder but I'm not sure which one to get. I don't want to fall into the hype of the Flip because I worry two hours won't be enough. What should I be looking for when considering a small camcorder and where can I get a good quality one with expandable memory? Thanks!"
No way in 2-3 years.
Even when that becomes possible, it will take a long time for people to become aware of it and prices will be high(just look at the prices for the fastest internet services). Not to mention that most people still want something tangable for their money; the downloadable music effect doesn't apply to moviies as a direct comparison for many reasons: size, age group making the purchases, portability(most don't want to watch a movie on a small screen but they also don't want to carry something bulky). they presently aren't 1080p, ..i could keep going on but what for; you're entitled to your opinion.
