While I had the I-40 and I will say that it did like it's sun light, I never had the problems you seem to be having. I really don't think the I-60 is much different than the I-40, except for the megapixels. I still think you had some bad luck with the units you had. I hope this new camera works out for you. I know how frustrating it is when things don't work as they should, especially at this time of year. Good luck with the new camera.
