Not long ago, I was ranting about how annoyed I was at the people who run FlipVideo. I have to retract some of what I said. I just bought another one and there are NO problems interfacing with iMovie.
After shooting your video with the Flip, you plug it into your USB port and quickly and easily drag the video into iMovie.
For grabbing quick, decent quality video, you can’t beat the flip. I haven’t got the new iPhone yet, so that’s what holding me over until then Another $200 sucked out of my wallet!!
