One more thing, to help alleviate your ignorance.
I have built dozens of PC. The ability to upgrade was necessitated primarily by Microsoft and software companies. I would buy a loaded PC with a killer video card and 18 months later the newest game or video editor would require a faster card, or more memory, or a faster processor. If I were unable to upgrade, my PC would be a paperweight in two years.
Currently own/operate about a dozen Macs and a couple of PCs. After about 5 to 7 years or so (Swordmaker has a better handle on that time) Apple will stop “supporting” a machine. It will still work, you just can’t upgrade the operating system any more. I have a Mac Pro I bought in 2007 that is still chugging along. I run Adobe Design Suite on it and use it for email and web surfing.
Macs aren’t up-gradable (a debatable point, they are to differing degrees) because Macs generally don’t need to be upgraded.
Nonsense.
I’m using a 2007 MacBook. Changed the HD to 500gb. I’m on the third battery and it only lasts about 1.5 hours.
I use Firefox and some other workarounds, but it’s still chugging along.
About $900 over 10 years...not too expensive.
The hammer bulged/tig welded covers were a bear to install and looked like hell.
