Thanks for your reply!
I also travel a lot, and I don't want to change computers and exchange data and stuff. So desktop is not an option. In my main option I have 27" screen to work on.
Looks like on the data sheet the windows laptops are better, do agree though built quality is not on the mac level. What I worry most about is the windows os, as I really like MacOS. Could get used to it, not sure about performance compared to each other.
I started to use C1 as my Canon 5dsr and fuji files look much better, tethering is also good. Might jump back to LR if they should improve. Then of course PS and sometimes Phocus for my Hasselblad.
I switched on open cl support in the c1 settings, and that was making my system about 10 times slower as my GPU seems outdated. The ATI strategy from apple is also not convincing, even on the C1 with opencl it might be less of an issues then with LR.
Might wait for the lenovo p50 or what else is coming with more memory and latest processors. They will be heavier though.
It's really confusing with all those cpu and gpu types in the laptops, so many seem to have different version even with the same model name.
