I think this is a fantastic deal. The E-M10 (review) is a slight simplification of the E-M5, which was the camera which brought the Micro Four Thirds camera system into the professional sphere. (I think the only significant differences is that the 10 is not weather sealed, and the Image Stabilization is slightly simpler.)
If you combine this for example with the outstanding, compact portrait- and all-round fast lens 45mm F:1.8, you will have a flexible and powerful system capable of professional results (sharp portraits with blurred backgrounds, and a general zoom) for under $1000. And it is even much lighter and more compact than DSLR cameras. And of course you have what is now one of the widest and best selection of lenses on the market, going from good, compact lenses, reasonably priced, to more expensive lenses which are amongst the best money can buy (no joking).
