Well, if you are going to be shooting any video with your camera, you might have problems importing the video files into iMovie. At least thats what happened to me... my Cybershot DSC-N1 records in a muxed MPEG video format, which means that it has interleaved audio and video tracks (they're mixed together instead of stored in separate tracks), but all i have to do before i import them to iMovie is convert them to MP4 using MPEG Streamclip. Other than that minor inconvenience, i have no problems with compatibility. Maybe that is what the salesperson was talking about.
