Just got my hands on a G1X, we bought it as an upgrade for our G12. Haven't had much use yet but my initial impressions are very good. The camera is solid, impeccably built, and seems to function way better then the G12. It rivals my 450D *(rebel XSi) for IQ and ease of use. It looks like this is going to be a great addition to my bag of stuff... and a go to for something that you can stick in a small bag if you don't want the large DSLR for some reason ...
Heres a pic...
If people are interested i can give a run down of how it is ...or answer specific questions if you have any!
