I think this sort of criticism of Apple usually lacks much substance. Everybody know what Apple products are, if you want something that’s highly customizable and easy to upgrade then why not just buy one of the countless different products that offer those features? Apple’s products tend to work very well, are typically well made, and reliably last a rather long time. I personally enjoy working on them more than any Linux system, so I buy them for that purpose. If I wanted a computer to tinker with, I wouldn’t buy a Mac.
