I think my next purchase needs to be a display calibration tool, but I'm having trouble finding a good comparison of the different brands and models. Even Spyder's website doesn't seem to have an easy-to-read chart of the differences in features in their models. I see a lot of posts about "I bought ABC and it's good" and "I bought XYZ and I like it" but rarely do people elaborate on the specific reasons for their choice.
My only must-have requirement is that it must work on multiple computers: I have a MBP laptop (no external monitor yet, though one is on my wish list), and my wife has a Mac Pro with two Cinema displays. We also have a rarely-used iMac. I'd like one device that will work on all my Mac displays.
I probably SHOULD have something that will auto adjust screen brightness based on ambient light levels, as I have big windows near my workspace. I think the MBP laptop will already sort-of do this - maybe using the built-in camera at the top of the display?
I'd like to keep it under $100 or maybe $150. I'm OK with used gear or last year's model.
Thanks.
