Got my GR on Saturday, extremely pleased with it so far, it really is fun and intuitive to use, I've put a 'mini-review' on DPreview
here reproduced below. BTW I couldn't see any mention of GPS options in the manual, although I know it was mentioned in the press release.
Mini-review:
"Excellent pocketable compact design, about the size of an audio cassette box, very light, well put together all metal construction apart from the pop up flash which is plastic as is the battery compartment door. Great big bright LCD screen, firm positive feel buttons. The main mode/control dial has a lock so cannot be accidentally moved, excellent 'adj' control wheel under your thumb which can be pressed and/or rotated to access menus, and a front control dial for aperture or other functions. Very intelligent control layout.
Power on time is a little over a second, focus/lag time is good, maybe a tenth of a second? I'm able to grab the GR out of my pocket, power on, take a shot and put it away in about 4 or 5 seconds. Fast enough for me. Image quality is great, nice graininess to images -a different look compared to all other digicams I've seen, beautiful wa lens. I'm confident I could go to 16x12 prints. Noise is not an issue up to 200 iso. 400 sometimes needs work, 800/1600 are just fine in b&w or with noise ninja etc. Prefer the grainy high iso on the GR to the 'painted' smudged look of the Fuji F11, the only other high iso compact competitor I'm aware of.
Problems
Sometimes auto focus locks on a peripheral object rather than where the on-screen cross hairs are positioned, suspect this is due to light/contrast levels of the peripheral object. Something I've encountered with all AF systems to some extent. Not a big deal, only happens sometimes in difficult light situations.
RAW write times are very slow approx 8 secs per file, which is a pity, as it makes using RAW unviable for me, fortunately the fine jpegs are excellent and artifact free. It would have been nice to be able to routinely use RAW but it's just too slow."
