I just recently upgraded from the JVC Everio G-M30 to the G-M60. The biggest difference between the 2 is the size between the Hard Drives (7 hrs, 30 Gigs for the M30; 14 hrs, 60Gigs for the M60) however, the best upgrade to the Everio series is the easy to use touch sensitive controls. All of the menu, light, and resolution features a scroll bar that is touch sensitive to change the effect almost instantly. No more "joystick" control, or controls on the back of the camera (exept for the record, zoom, and pic features), everything is right there at the "touch" of your hand! As for the size...It is extremely small at approx. 8"x6"x4" and around 1 pound of weight it's the perfect camera to grab and go! Highly recommended, unless you afford one of the Everio HD HDD Models!
