Just a quick note: you MUST shoot RAW and process via SPP with these cameras. The JPEGs are indeed fairly soft and lacking in DR. A properly functioning DP1M will be quite noticeably sharper than a M8. It's also a fair sight sharper than my XPro. Of course, rendering is a little different, and beauty is in the eye of the beholder, there. Sharpness isn't everything.
In any case... I've had my DP1M for a bit now and have enjoyed it quite a bit. I don't find focus to be too bad; in decent light it's quite good, in poor light it can hunt but the MF implementation is so much better than my XPro I don't care. Magnify in MF with a touch of a button and on half-press you get the full view of the frame to compose. Brilliant.
The camera in operation is quite fluid, and although it takes FOREVER to view a photo you just shot (you can keep shooting while it writes, just not view), the AF is far more accurate than my XPro so I don't feel the need to chimp. Shoot it like film.
I personally find the files beautiful, very much like slide film.
The negative is its very much like slide film!
I really love 28mm so I started with the DP1M, but I love the output so much I grabbed a DP2M at B&H's sale to put under the Christmas tree. I foresee using them quite like my XPro with the 28/50 duo.
Here's my shots so far on my Flickr.
I haven't had time yet to take it into its natural element, but so far I've enjoyed it just for daily life photography.
