The image sensor on this camera is much larger than those in any smartphone, so the image quality will almost always be better.
I have really large hands, so I battle with holding smaller cameras. With the R100, however, it only took a few minutes for me to get used to how it feels.
A camera has to feel good in your hands; I don't care about its elaborate list of bells and whistles, it should just 'feel right' if you're going to shoot with it regularly.
The ISO was cranked up to 3,200, so getting image noise is almost guaranteed. Look at the first image and compare it to the zoomed-in version of the image below. The noise isn't much of an issue.
