Photos from the G1 are good for snapshots at small sizes; poster-sized prints and heavy cropping is probably out of the question. As with most point-and-shoots, quality drops off above ISO 200. The bigger problem is that subjects have a decidedly digital appearance. Add to this the increased noise and noise reduction from ISO 400 and above and your chances of getting a sharp, detailed photo are almost nonexistent. Of course, these issues aren't as visible at smaller sizes, say prints at 5x7 inches and below, or when viewed at similar sizes on a computer screen. Also, beware that with the starting aperture of f3.9, low-light situations will force you and/or the camera to use higher ISO settings or the flash. There are noticeable color issues at ISO 1,600 and ISO 3,200 due to noise and yellow blotching.
