Main disanvantage of K1 is that I think I have to also change almost every part of my computer then, and that might cost extra 1000€... I think I should anyhow change my two 22" 200€ monitors to one better, maybe wide screen monitor with decent color rendering.
I have AMD FX 3.6GHz, 8 core + 8GB RAM + 1024MB ATI AMD Radeon HD 6800 + Lightroom CC. Windows 10. I can wait for Import/Export, but if handling and adjustments starts to stuck, I will lost my marbles.
If/when I buy aps-c, I will (yes I'm an engineer) always think what I'm missing with cropped body? Will K1 make better quality? With K1 there wouldn't be any room for explanations, I would only blame my self.
Then again, if I decide to go for dark side and change almost every gear, here in Finland is lightly used Nikon FF sets with bunch of lenses in markets under price of K1 body...

Image quality and Bokeh is everything for me. Currently I shoot over half of my shots with manual focus, so AF speed is mostly irrelevant.
