Robert, I've been in the same boat. Loved the images I took in 2012, but did not want to carry the full sized Canon again.
I've just bought a Sony A6000 a few weeks ago. Camera, with battery and card and 2 lens comes in at 1.5 lbs. Charger and 2 extra batteries keeps everything under 2 lbs.
I give the camera 5 out of 5 stars considering price and features. 24 MB raw images, lots of control and shooting options. WiFi works well, and uploading to FB is easy, as is copying to a tablet, PC, etc.
My plan, which I have thoroughly tested, is to copy images and videos to my iPad with the camera connection dongle, then upload from the iPad to Dropbox using CameraSync. RAW files will appear in the iPad Photo app as jpg, but CameraSync will find the full RAW and send to DB. One hitch so far is that videos must be mp4 to load to iPad, so I'm taking an extra SD card for AVCHD video of special events and places.
The camera is great and fun to use, though the learning curve has been uphill, because I'm not used to a lot of the Sony terminology and features. Actually, I'm backing away from some of the wiz-bang features and going back to basics with the camera now. (What was I thinking?)
I researched the whole batch of mirrorless cameras before deciding on the A6000. This is a whole new world for digital photographers.
Anyway, just some thoughts and experiences. Photography is part of me, and if you are the same, you'll figure out a best setup for you. The images I brought back add so much to my ongoing appreciation for the Camino.
