Photographers and graphic design folks care!! Color management and consistency across devices is a huge issue when dealing with digital images. You want to make sure that shade of magenta looks the same, no matter if it is on a Mini or an Air 2 or your calibrated monitor at home. Especially if you are going to use a Mini for photo review in the field or portfolio showing to customers.
Much wailing and gnashing of teeth goes on about reaching color management nirvana in the photography forums I participate in. ;-)
