I have done, and I don't find them appealing, sorry.
I'm afraid that I am a bit of a control freak - minimalistic high quality cameras that have dedicated shutter speed, aperture, ISO, exposure correction dials, a single af point with focus confirmation for non-af prime lenses and a large bright viewfinder (evf or ovf) would be ideal. Accurate ISO is useful so that I dont have to rely on the camera meter for bif and can use my incident meter instead.
The nearest being the Fuji X series of which I own one or two, but unfortunately don't include an slr, but I am tempted by the EVF models - maybe...
I used the original Pens, but despite several trips to buy one, never bought an F (the slr) as I prefer bigger 'bits' when using an slr under duress. The OM family were far more useful, with a huge range of lenses, most of which I owned at one time or the other.
The E-X00 series were about the right size for me but were never sealed against dust or rain, I still have several bodies which still get used. The E-X series started out the right size with sealed lenses but got too big subsequently. All my macro lenses are 4/3 or OM with convertor, and I still have my weather sealed 4/3 lenses which suit me fine. The in body image stabilisation works for me as well.
I am down to 2 M4/3 bodies now as I really do find the lenses too small, & while the latest bodies are sealed against the elements none of my existing M4/3 lenses are.
And in case anyone thinks that I am totally obsessed by Olympus I have used, owned or still own cameras from most of the major manufacturers and have simply used what I like - and could afford. No Hasselblad just yet (£14,000 - £30,000 body only!).
My real problem are the thousands of photos I have accumulated over the years...
