Sony Cyber-shot DSC-T70 Digital Camera

I have this DSC-T70 and I think it takes great pictures and all except for one thing. I have large hands and my fingers always seem to get in the way of the lens and into the pictures. I noticed that the lens is too far to the left of the camera and when holding it, my fingers extend over the lens most of the time. Sometimes when trying to catch a fast shot, I don't always look quick enough and my pictures have partial finger blotches in the upper left side.
I also notice that after a few days, the surface of the touch screen window was getting scratched. I went to a camera store and purchased a package of thin protective cling covers to cover the window. These can be scratched and then changed as necessary. I think Sony should have included these in the price.
