A k-1 with customized android system built in is not a bad idea indeed!
I don't need to play game or write a book on it. But if I can light edit the photos, upload some here via wifi or 4G cellphone SIM card... GPS navigation and tracking, with apps help me finding right time and place for perfect light... Navigate through gallery, find a photo, and can do 2nd or multiple exposure on top of that...and maybe built-in small projector to share photos at camp site...don't mind playing some music...set camera on tripod and go sleep, camera wake up at 5:30am and take some photos, before sunrise, a few more at 5:45 am, when I am still in sleeping bag
, ....connect to a motion sensor and take some pictures of animals in the dark...
DSLR has bigger battery (more batteries in the bag, easy change in 3 sec) and more space, why not?
