I just got a Surface Pro 3, i7 256gb model about a week ago. I'm a photographer and retoucher. I got the Surface mainly to do retouch while traveling. I haven't yet got to try it out for real in Photoshop for any long periods, as I'm a mac user I constantly press the windows button and it gets pretty frustrating to getting used to the switch of the three buttons next to the space bar (by the way, is there any way to change the keyboard to mac-style?). I was trying out Photoshop CC 2015 on a pretty high-res image (about 6600x4400 pixels), in the 8-bit mode. I did some simple clean-up with the clone tool and healing brush tool, and I also used the pen tool to make a path. I was only working on one layer on the image so the file itself wasn't really that big. I noticed the fan started working after only a couple of minutes. I thought it was a little weird as I only had one layer. The fan wasn't really going that loud, but still I could clearly hear it. I don't expect the Surface to handle really large psd-files that good, I just want to know if this is normal? And do you have any tips on how to optimize my photoshop-settings to get the most out of Photoshop on my Surface?
