My experience of people in the design industry that use a PC (Microsoft Windows computer) is that most of them have little idea about usability. BIG HUGE SWEEPING STATEMENT!! I know… but it is my general experience that people who spend most of their time on Macs, will just by nature design things that are more usable… yes, I am frustrated at work right this second… yes, people will most likely flame me for this… yes, everyone in the design industry who uses a Mac will probably agree!
The Mac OS X and its developers generally understand people better.
There you go, I said it!
