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!"
Yeah, I was going to post the same thing. As big as Iron Man on Blu-Ray was, the Dark Knight will shatter this record.
The combo of the Dark Knight on Blu-Ray, the Holidays, and possible lower prices could really give Blu-Ray a huge kick this season.
