X Pro X-E1 raw files
Fuji X-cameras includes Silkypix, so unless you don't like that software, you don't have to buy more software to process RAW. Once converted to JPG or TIFF, or using OOC JPGs, your work-flow will then be the same with older versions of LR or PS.
Silkypix is not the monster than many complain about. No more awkward than switching from PS to Capture One and figuring out it's interface.
