I must be like the only person in the world for whom the following is true, judging by the responses in thread:
1. I have a 5 year old PC.
2. I upgrade my drivers regularly because its extremely easy to do so.
3. I have had almost no hickups "installing" things.
4. Generally, new games choose optimal settings that work just fine for me.
5. HL2 EP2, Portal, TF2, and all the other recent games I've gotten installed and play without a hitch.
I have never experienced what you call "Installation Errors" or "Patching Issues." Its really not hard to keep your hardware up to date, and even easier to patch games these days with all their nice autopatching features.
That being said, I love my Nintendo Wii as it provides a gaming experience that I've never had before. I love my PS2 because of the catalog of great games that I'm still working through.
But I still primarily play games on my PC.
