alright then, we'll make a big deal out of power cables, if thats what you really want to do:
The power cord problem is just one example. The fact that Apple is such a proprietary entity, means that many of the stuff you need for it costs more, because it 'has' to be made by Apple.
Apple won't let third parties make aftermarket stuff for them. It's sort of like Nintendo now with the Wii/U.
Here's another example;
my sister just got the new iphone 5. I can't remember what the product name is, but there's a hard protective cover you can buy for any smartphone. My wife has the Samsung Galaxy 4, who also bought the same protective cover designed for her smartphone.
I don't remember the actual dollar amounts, but guess which one was literally HALF as expensive? The Samsung.
There are countless other things that cost a stupid amount because 'it's apple, stupid'.
I am by no means a master of computers, and I don't pretend to know as much as you, but I have seen enough from apple to give me the facepalm and make me never buy another apple product again.
Edit: I tell you apple is too expensive, so your solution to the power cord problem is an even more expensive product? Yeah, no.
