Yes, I have tried calibrating my laptop screen using the default Windows 7 screen calibrator. Calibration has a lot to do with ambient light in the room you are working in, does it not? So any time I move to another location, my screen is ‘uncalibrated’. Plus, I think the angle of viewing has more to do with it than anything else. Your picture can go from overexposed to high-contrasty underexposed just by tilting your screen! I’m not really that worried about it, since the printing I do, I do on a printer from some company which won’t be calibrated to my monitor anyway! Not to mention, that last time I printed, I designed the files in the RGB colorspace, and the printer wanted CYMK! That really doesn’t make for accurate colors! Sadly the GIMP doesn’t support CYMK, so there’s not much I can do about it!
