I have had my HMC40 for over a year now and I love it. I do a lot of outdoors shooting, mostly scenic nature shots. The one thing you need to know is that it lacks in low light capability. So if your doing a lot of indoor with low ambient light you will want some form of light kit to take with you.
As for ease of use, when fully automatic it does decent for a run and gun. Being a lower end pro camera don't expect a typical point-and-shoot. You will get the occasional gain/level/focus hunting on any rapid scene change. It is not a camera you would take to a critical shoot right out of the box. You will need time to learn it. Stills (at 10.6 Mp) are really good. Nothing like those from a DSLR but they make great fixed frames for the videos.
I take mine out to the backyard a few times a week to "play around" and try new/different settings. I have learned about half of its features well enough to work by touch, but those are the ones i use just about every time I am out recording with it.
So a lot will depend on what you entend to do with it.
Life is not a guided tour nor a destination.
It is a journey. Take the time to enjoy your family, friends and surroundings.
Build memories. Share experiences. Travel at sight speed not light speed. (C)
