A revolutionary camera - for landscapes & travel

I have a Sigma DP2 Merrill in August 2012, and have taken well over a thousand photos with it so far. This is truly an amazing camera, and as much as I loved my Canon G11 (I'm an enthusiast, by the way, not a professional photographer), the G11 has sadly been relegated to a mere backup camera.

The DP2 Merrill seems comparable to a mini medium-format camera: the images produced are absolutely stunning in their detail and rich colors. I initially worried that the lack of a zoom lens or the ability to change lenses would be limiting when I compose photos. However, I later discovered that there is so much detail captured that the 45mm (equivalent) photo turns into a telephoto and macro lens in post processing. In fact, many of my photos contain details that I never saw when I originally composed the shots, and zooming in to discover these treasures actually makes post processing a lot of fun. (Really!)

Since the bulk of my photos are travel & landscapes, this is truly the ideal camera for those purposes due to its small size and image quality. I am more than willing to live with some of the shortcomings because the end results are not only visuallly stunning, but invite further exploration of the details long after taking the photos.

Problems:

Here are my top 10 problems and annoyances, in order of priority.
1. No image stabilization. I hate using flash & don't own one for this camera, and I really don't like bumping up the ISO when there's not enough light. A tripod is a must in many situations. In some cases, I just used my old camera (Canon G11). This camera is fabulous in good lighting, but not so good in low light.
2. Auto white balance is not as good as I had hoped. I spent an inordinate amount of time post processing images to correct white balance. The bigger name camera companies (Canon, Fujifilm, Sony...) seem to have much better "out-of-the-box" auto white balance.
3. User interface. It's not too bad, but there is definitely a learning curve, and in the first couple of days I found that I was inadvertently taking photos with the wrong settings. It took some practice to remember what to look for.
4. Speed. The raw files are so massive that it can take a little while for the camera to save the photos before I can switch to playback mode or turn off the power.
5. Accessories. I bought the DP2 Merrill at the low introductory price, which I found out meant that there were no accessories available to go with the camera. It was a scramble to find compatible batteries, filters, & case before leaving on my trip. Thank God for the Internet and Amazon Prime shipping.
6. Too much detail for portrait photography. People really hate displaying their pores, scars, wrinkles, etc. to the world.
7. Battery life. Yes, the batteries run down fairly quickly due to the huge file sizes. I figure an hour or two per charge, depending on how much I play back the images. On heavy sightseeing days, I burned through three batteries. It's a good idea to have at least 3 batteries and 2 chargers when travelling. On the bright side, the camera will warm your hands on cold days!
8. Sigma - will you please share your proprietary raw format with Adobe?
9. File sizes. A 32GB card will last only a few days of sightseeing if you take raw photos. Also, if you haven't upgraded your computer recently, you might want to go ahead and do that for this camera. Try an SSD for your OS and program files, and a second mega-huge drive for saving your monstrously large images. Don't forget a fast processor and lots of memory, too.
