The G7 looks really interesting as Canon seem to have ditched the loathsome CADD (Curse by Auto, Delay and Delicate) agreement that have made compacts almost unusable in a manual mode if they had it.  

All digital compacts had to be built to CADD standards, meaning Auto everything and if manual settings were included they had to be difficult and unrewarding to use.  Well done Canon for ditching it when they built what from my short trial with it seems to be a very nice piece of kit .
