Wait. You start your rant complaining about Apple not using, according to you, "a common charger" and how that decision is why you don't buy their products and how that is a "free market" choice.
Then you complain how other people, exercising their "free market" choice and choosing Apple's products is somehow wrong because Apple is greedy and charges too much for their software. Wait, I thought we were talking about chargers.
Sorry but, what expensive software are you referring to exactly. Their operating systems? Can't be that, they don't charge for their operating systems. Must be their other software, Pages, Numbers, Keynote, iPhoto, iMovie, GarageBand, iTunes or Xcode? No, those are all free as well. Must be their professional software. Final Cut Pro $200, Motion $50, Compressor $50, Logic Pro X $200, Main Stage $30, Aperture $80. Those seem considerable less expensive than the competition. I'm sure if you did a comparison you'd agree with me.
It seems you support the free market but only if that free market agrees with you and if not then regulations should be used to force the corporations to bend you yourumm, I mean, I don't know what you mean anymore, you're all over the place.
Back to chargers for a second. What determines "common?" Apple has used only two different connectors over the course of about 11 years. The 30 pin connector that originated on the iPod and was used on a few generations of iPhone and iPad and the just recently introduced Lightning connector that now spans the entire current range of mobile devices. I think that's a pretty good track record.
Now let's contrast that with the history an plethora of connectors that were common on other mobile phones and devices. Even amongst a single manufacturer it was common to have different connectors amongst different models of products released in the same year let alone the fact that it was also common to change the connector every 2-3 years.
How about Apple's laptops. Apple introduced the MagSafe connector in 2006 and used the same connector across all its laptops. It wasn't until 2012 that they changed to a slightly thinner design to accommodate the thinner profile of their newer laptop computers.
