I don't really get the video thing. I much prefer pictures. My wife runs the video camera and records everything. I tried giving her tips similar to those above, but she wants to record eveything... EVERYTHING! I keep putting off the editing though. I just have too much going on.
Finally, I'll be able to carry just one camera again... certainly makes the choice in DSLR's a lot more in favor of Nikon. I have not tried it yet but I will let you know if it's truly worth not carrying the Mini DV around anymore... I'm thinking this being first gen for this mode that it will only get better in the follow up models (hoping!).
BTW, I took look at the new D90 today and found out it only takes 5 minute clips but for me that is plenty long enough... I could stop carrying around my camcorder! I think I just found my Christmas gift to myself.
