Macs indicate 24-bit color depth by using the term "millions of colors", while Windows calls it "24-bit" or "32-bit". (I'm aware that Windows "32-bit" color simply adds an alpha channel that doesn't really add anything to the color gamut, but eases the display of transparent objects.)
While the term "millions of colors" is readily understood by inexperienced computer users, it may be less precise than "24-bit", especially to more experienced users (224 = 16,777,216). Should technical concepts like these be simplified to ease understanding at the cost of precision?
