I'm a multi system user, what i mean by this is that I have an olympus epl1 and OM-D, but also the X100s and Im loving the setup as I like my M-43 setup for action and the x100 for more candid/street work. I find that the OMD is great for action and long distance because I can configure my body How I need, but its not that great for candid work as it is a bigger setup. I Do have to say that both give great results and that i love them both. I do have to say that I'm surprised that I'm using fuji as fuji had a while were they were not that great. If anyone uses more then one system or wishes you could, post your thoughts below.
