Tiny1 looks interesting
The Fujifilm X series are pretty decent, I have an early model the X-E1, better Ha transmission than many, the only downside is that there was no tethering support until the very recent models, although I believe there was an app available for wifi control (just not for the X-E1!).
Having the interchangeable lens ability is a bonus, and with a pancake lens they can (almost) fit in your pocket...
