I'll be buying a 27 imac soon and want to upgrade to a new HD camcorder. 2 questions: 1. if i burn hd video with the built in superdrive, that won't truly be hd, right? i need to buy an external blu ray burner to get full hd quality? 2. how happy are you (are how unhappy are you) with your hd camcorder and/or choice in media used by that camcorder(tape/flash/hard drive)? just looking for opinions, I don't want a cheapie, flip camcorder but don't need to spend over a thousand for the best, either? any other advice on what to buy or upgrade... i hope to do this purchase right and be happy for quite a few years with the new mac and camera.
