I started using my G3 400 for DV last October and enjoyed it so much I convinced my company to buy a iMac DV SE for producing some promo videos. Both worked equally well, but I've added an additional 36 GBs of hard drives and an additional 320 MBs of RAM to my G3 over tha last year in order to accommodate the amount of video I work on at home. My DV SE has nowhere near the amount of easy expandability, especially when you can't plop down a bunch of cash at once.
