Nex 6 Info and Purchase Help

I am having a difficult time deciding between this camera or the Oly E-M5.  I think the Oly has the edge with lense selection and the in body IS.  But there is something I really like about the Nex and am wondering if I would find using unstabilized lenses a problem with this camera (I'm approaching geezerhhood).  I think this is the biggest thing holding me back from pulling the trigger.

Anyone here own both or used both?

Thoughts on user experience with the Nex would be helpful, especially opinions on what may be lacking.

Thanks
