If that's the case, the price don't sound too bad. But still, take your time to evaluate. But for most scenarios, mirrorless like em10 really gets my vote.
The longer you carry something, the heavier it will be... every bit counts. Carrying a ~2kg load (minimum) everywhere you go is really troublesome. Not forgetting if you are going for a long shoot with tripods, filters, water, extra lens, etc. it's easily going to be a 6-8kg bag.
For the ergonomics of the different camera, Preference really differs from person to person.
Actually I have the 7D, still using it and still loving it. However the camera technology is really kind of old and I do believe that 70D had a newer and better sensor, low light performance is better. If you can afford the 70D, get the 70D. As for the AF points, they should be about the same, as for liveview focusing, 70D wins hands down. All in all, 70D only lose slightly in the weather sealing department.
Now... if you are looking at 7DmkII, that is a totally different beast altogether.
yup, 2 major factors that prevented me from getting a DSLR are the size and weight. not long after i gotten my EM10, a friend pass me his Nikon D800 to help take some photos, after 10mins, i gave it back as my arms are feeling a bit tired and the weight/size makes it cumbersome to manouvre. after this, i am really glad to have the EM10, always quick on the draw! of cause the looks and price of the EM10 plays a big part in my decision making as well
Shoot from far or quite close distance?
If from far u need fast long lens that is 70-200 equivalent of full frame. Then I cannot imagine u use big dslr lenses that is not only heavy but also attract attention.
If I am able to disuade my wife to use e-m10 with 35-100 f2.8 instead of her using D300 with 105vr micro on street, means it is a good setup.

In the top diagram you see the signal to noise ratio. 7D performs the worst here, followed by E-M10, then 70D. In the bottom diagram you see dynamic range, where the E-M10 has some advantage over the Canons in the low ISOs, but the performance at high ISOs is similar to the trend you see in dynamic range. Looking at the diagrams, the 7D has the worst sensor, which is expected since it's a significantly older camera than the 70D and the E-M10.
Take note that sensor performance is not everything in a camera. All 3 cameras are very capable, but my personal recommendation would be the E-M10. Even though the price your friend offered you for the 7D is not bad, I feel that most of the features the 7D has are catered towards sports photographers. Which means most of the advantages that the 7D has over the other cameras are of not much use to you. I've also mentioned before why I don't recommend the 70D line due to what Canon is doing with it.
ISO: At high ISO (e.g. ISO 3200), I seriously doubt that the 2 models you are comparing have that big of the difference to justify if one is better than the other.
AF: If the subject you are focusing at has poor contrast (e.g. a black wall), I believe none of the auto focusing system in the world can get that focus right. Given enough contrast, I think both should perform similarly. *At most add a LED light to light up the focusing area lar... confirm the AF spot on for any system*
