Got mine on Friday after playing who's got the package with the post office.
Initial reaction, well worth upgrading to. The new layout of information on the screen is much more usable, seems better at higher ISO (can not confirm this my iMac died Saturday morning), the setting of the distance for Snap is to my way of thinking a big improvement and yet it retains all the features and pocketablity of the II.
I'm happy to see Ricoh working to refine the design rather than just adding more bells and whistles.
Once I can get the iMac fixed, the GR-DII will go on the block and I'll have some images to post.
Does anyone know of a good little case for it with a CV Min 35/28 finder on it?
