My wife killed another compact. 
So with our ELPH 100HS being deceased, we now have just the EOS M +22mm and the 60D with some lenses. She rarely uses the 60D due to size, but she kind of like the EOS M. However, with just the 22mm, it isn't as flexible as I'd like for outings and travel. She also needs Wi Fi to transfer photos to her phone for instagram, etc and we've been using a 4GB Eye-fi.
So I'm thinking I could either add the 18-55 to our EOS M kit and buy a bigger wi-fi card, or just buy a new wireless compact like the ELPH 320HS, 530HS or similar. I wonder if the 18-55 might add a little more bulk than we'd like, while still not giving much zoom, even if the quality is better.
So the short version: What's going to give me the most versatility for a travel/walkaround kit? EOS M +22mm and a compact or EOS M + 22mm +18-55?
