I don't regret purchasing the A6000 but it's really important to know what the intended use will be for your camera. The RX100 is nice because after you buy a screen protector, extra battery, possibly an aftermarket grip, you're done.
With an interchangeable lens system, there's always another lens on the horizon. I think Sony realizes that they need to invest their resources, heavily, into getting their native E and FE lenses up to snuff compared to M4/3 and DSLRs. Rumor has it that they are aware of this and to expect several more lenses to be released within a year.
If you're fine with manual focus, then the sky is the limit. If you need fast auto focus telephoto lenses for sports, birds, etc, well… then it gets a bit tricky.
For me, I'll likely buy the sony f4 70-200mm for sports (hockey), and am looking at the sony 90mm macro with great interest. And then there are a few Voigtlanders. And a few Zeiss lenses. But then I'm not finding an ideal wildlife option as the current adapters reportedly suck (and I'm not crazy with the Sony/Minolta alpha mount and adapter options) so now I'm looking at Canon APS C bodies and their 400mm lens with 1.4 teleconverter. And on. And on. And on.
It's a sickness. Get the RX100 and get out while you still can.
Joking, but just a little.
Edit to add: I'm projecting a lot there. You've already stated that you're not looking for fast auto focusing telephoto lenses, so there are a lot of great options out there for the A6000 that would cover wide angle with the occasional shot of a hiking buddy. Long story but I had the RX100i for a week and think it or any of the subsequent models would be ideal for this too as a smaller/lighter option.
