This was one of the sticking points for me. When these came out around Christmas, I really wanted to jump on it. I spoke with a friend who is electronically smarter than I to get his opinion and he said to wait a couple of years. They record on smaller discs---not the same standard DVD size disc (I'm pretty sure about this, but not positive!) You would have to transfer the digital info to your computer and transfer to a disc.
Overall, he said the technology is newer so wait a year or two until the companies have the kinks worked out. It looks great, though. I'd like to hear more about it. If you can't delete them from the smaller disc, can you ever delete them???? i.e. if you were to transfer the images to a larger DVD??
