Computers are, as a rule, just awful. Mostly because humans are idiots or just plain greedy and cheap. Funny thing how the Ubuntu installer asked me if I wanted it to download updates and I said yes and then after it is done and I do sudo apt-get update ; sudo apt-get upgrade there are a zillion things it wants to update after all. What! Ever! Don't even get me started on how "just" adding in a pci-e nvidia graphics card causes the machine to lose all ability to actually, you know, display anything. Etc. ad nauseum.
