Is there a point to this thread?
When people talk about PCs, they refer to the computers built from a series of individual parts which are easy to set up and upgrade. That's why they say a PC is "the sum of its parts". Usually with Windows, sometimes with Linux, sometimes both, and sometimes "hackintosh".
When people talk about Macs, whilst they are technically "Personal Computers" too, they refer to the overpriced premium package that is Mac hardware and OSX. The hardware is very difficult to upgrade and by the time some part goes wrong (take, for example, the PSU of my Mac) and you take it to the Apple store, they tell you that the price to fix it is so high that you might aswell buy the newer model (which in my case was 6 years newer). That puts the Mac at the same level as laptops for upgrades and repairs.
The above may not be necessarily correct, but that's what the general market thinks. Going any further is unproductive.
