I didn't spend much time on focus performance, but that's because focus acquisition seemed similar to the 16-50mm kit lens and isn't really spectacular, but it's not horrible either.
If you shoot sports or wildlife, and enjoy the 1.3x crop factor inherent to a DX body (and are willing to sacrifice the high ISO quality using DX vs FX), the D500 is the best camera you can buy today.
It took great images, but pocketable it was not. The S95 fits the bill perfectly, as it is extremely thin (and pocketable), and takes images that are nearly identical in quality to the G11.
