At one time Macs came with a bunch of ports, Apple Desktop Bus, AppleTalk and SCSI. Apple made a lot of people mad by dumping all of that for this new-fangled port called "USB." And then Apple dumped the almighty floppy drive, causing conniptions. Did you know no Apple product has shipped with a VGA port for years? Seriously limited connectivity.
I advised a friend of mine who wanted to look cool to buy a mac mini. He did. He was happy with it. He bought a used Apple monitor. Unfortunately, the particular Apple monitor was not immediately compatible with the mac mini, and he had to buy a very expensive adapter to get the monitor to work. He was one of the “help me fix my mac” people. And he didn’t consult with me first before buying the monitor.
So, yes, Apples limited connectivity options end up costing their customers a lot of extra money. Way back when, when apple was apparently using a bunch of proprietary connectors, it certainly was a step in the right direction for them to use usb.
