At ISO 1600 the image quality from the G10 is almost unusable. There is lots of ISO noise and very little fine detail available. The 1000D on the other hand is quite impressive, with ISO noise quite low, and most of the fine detail retained. The larger sensor in the 1000D again is showing its benefits. For the same, or similar, money the image quality difference is huge.
