Summary: I have read some of the negative reviews posted for this camera as well as the HM320 and HM340 (which are identical cameras with built in flash memory). First, I think the "haters" need to understand where this product is positioned in the market. This is a mid-level consumer grade HD camcorder, that has been market down to ~$200, making it an entry level price.
Pros: It gives good video and focusing with good light, 4 quality settings, 3 hours on a single charge, easy to use menus, good audio, small enough to fit in a pocket, dual SD card slots, time lapse and it works with upgraded Window Live Movie maker.
Cons: My wish list includes manual focus, a microphone input, a headphone input, better image stabilization, better low light video quality, sharper still images, and the ability to focus in low light.
Summary: Just a point that I noticed while researching cameras- although the product description mentions the "Super LoLux with Back-illuminated CMOS Sensor" this particular camera does not have this sensor. The "big brother" does, and then this is listed under the advantages: http://www.amazon.com/JVC-GZ-HM550-High-Definition-Camcorder/dp/B0032FPYHY.
