As I've mentioned earlier I came back from my trip to Italy where I used my C6 a lot.
One of the part of my experience is I don't need card with capacity more then 2Gb at all.
Usually I've got stills and video no more than 2/3 of 2GB card per day shooting from 9AM till 8PM. I've got 4 card in 10 day-trip and now have 7.5GB of video and about 250 stills.
My conclusion: for me 2GB limit for card isn't critical issue for C6.
Much more important ones are:
- 10x optical zoom and
- viewfinder (for longer battery life).
Of course lowlight performance also what I want.
