i think with Olympus only having 3 models of the OM-Ds, EM1, 5 & 10, they are able to streamline their range for different needs and budget, yet providing very up-to-date technologies that even with the 'entry' level EM10 they also did not stinge on the features, design and built quality.
Not to mention that they are constantly releasing very good lenses, the pros and the primes.
I got the EM10, due to budget, but it had surpass my expectations and never regretted it. of course 1 of my main concern is the looks as well and it reminds fondly me of my old film SLR.
