* form factor like a flipcam * must shoot low quality video e.g. around 640x480 or 800x600... 15fps would be excellent, but don't think its realistic. HD only is unacceptable. * uses sd cards * waterproof * prefer removable batteries, but again, its likely this is unrealistic, as they seem to all have internal batteries charged by USB. * must have a way to attach a string to it so it can be hung around neck. * not sony bloggie (only HD, only internal memory, etc.)
I have one that I bought awhile back from a Staples closeout... Added a 8GB Micro-SD card, and it will do up to VGA res (640x480/30 FPS) until the battery runs out...
