I've got the G1x for about 4 months and I really like it. There is nothing to complain about except that it is obviously not a DSLR. For example, the viewfinder will not give you a 100% view. It only gives you a rough estimate of the view you will get, but we often trim and straighten our shots a little anyway. There is no need to get the perfect framing right away.
I accept the one fixed zoom lens solution because that is the only pocketable solution. With the SLRs, I don't have as much problem carrying some Nikon F5 as carrying a set of 5 lenses. So the small body solution is not attractive to me at all.
Without the mirror, I have no choice but to rely heavily on the LCD display and the flexible LCD of the G1x is very useful. I rarely hold the camera at arm length, it is better to hold it closer to my body and there is no need to use it at eye-level
The most important thing is the IQ which is a strong point of the G1x
People complain a lot about the slow lens F2.8-5.6, but have they compared the size of a 24-70mm F2.8 with the small 18-55mm F3.5-5.6? This is the thing we should accept to have a pocketable camera because we should not sacrifice other things like sensor size, or IQ. Besides, the lens of the G1x is a little slow but not a bad one at all. Remember what the max aperture of the Contax T2 you have is? The lens doesn't have to be big to give quality picture, but it must be big to be fast (unless it is for small sensors)
The AF is good and the quality of ISO 800 is good. The handling is good, buttons and dials are convenient. The battery life is surprisingly good , maybe because I don't have the habit of shooting randomly
To me your choice of the G1x is perfect
