Anybody out there go from a 1520 to an 830 ? Maybe your 1520 broke, or you just wanted something new, for whatever reason you switched..what do you like? What Don't you like? What do you miss? Or what are you glad is finally gone? What's better or worse? And what about that camera..is the 1520 camera really any better than the 830, when you look at them on paper you would think the only difference is that the 1520 pictures are simply larger/higher resolution, since they both have all the same camera bells and whistles... and is that one extra microphone the 1520 has much better ....I've had a 1520 and am curious of the 830
