1. true
2. true, but people needs to be educated that smaller camera = smaller sensor = bad low-light image quality. Just look at the number of questions asked on this forum alone about how bad their P&S camera taking indoor / lowlight pictures.
3. true, but they need to have their head examined. Any family ocassions (or any ocassions) that's worth recording is worth re-watching and be preserved as high-quality as possible. None of the current P&S comes even close to DVD quality, let alone miniDV.
4. this is a misconception, how more 'live' can a preview be than looking through a viewfinder?
5. there is no need for disposability and waste and the eventual impact to the environment when they use a camera they're satisfied to begin with (just look at how many threads complaining about shutter lag and startup lag)
6. there is no intimidation in using dSLR. That's why the manufacturers create the "green zone".
Just playing devil's advocate here.
