I have 2 d-40's and a I-40 (just less pixels than the I-60) and I have had good luck with all three. The D-40's are olderbut the I-40 has impressd me quite a bit so far!!! Battery life is good 2+months @ 1500 pics give or take. I am only using 1G cards.I am at work or I would post pics of both,I only have pics off the d-40 on my hard-drive.
