Read the internet camera forums for any length of time, and you will run across this exchange, over and over (with some variation as to make and models in discussion):
Q: "Should I get the M8 or the D3? Both have great lenses, both cost $5K, and both would constitute sufficiently badass additions to my 'arsenal'."
A1: "Get the D3. 12 fps, more megabytes, more weatherproof, more battery life..."
A2: "Better the M8. It's unobtrusive. You won't scare your subjects off when you bring it to your eye."
A3: "You haven't yet said what you want the camera for. It's horses for courses, of course. That's why I have a D3 and 200 F/2VR for shooting my daughter's middle school volleyball (they just don't light those gyms!), and an M8 and Noctilux for shooting trivia night at my local. You should think about this approach.
A4: "It's not the camera, it's the shooter. Just give me a first generation Digital Holgalux, and I'll shoot rings around all you posers."
A5 "Not to hijack the thread, but does anyone know if the new firmware for the D-holgalux II will fix the noise at ISO1600?"
My take? First off: "Arsenal"... bit tired, this one perhaps, lads?
Second: No, you don't take a gun to a knife fight; no, you don't take your Hyundai to the Nurburgring; and no, you don't need to have the perfect camera for every possible situation.
The point and shoot you have with you is going to make a better picture than the M8 or D3 or whatever you leave at home.
Wow, it feels good to have the last word on something.
