My brother has one and loves it. He does videos all the time for work (he works for a supplement company who also sponsors him for his bodybuilding competitions). He does videos of his workouts and has a video blog for his recipes! His videos always look good and it's super easy cause he can carry it with him (which is a plus cause his schedule is crazy!). Any specific questions you have, I could ask him!
They're no longer going to make any more Flips. But they are still selling them but are only offering providing technical support for both Flip video cameras and FlipShare until 12/31/2013. I have one and I still use it. It's great. Good news is that you might be able to get a good deal. Buy any accessories you can as they might be hard to find later.
