@meowshi: I get freaked out when my laptop breaks and I'm a computer engineer. There isn't much you can do as so much of computer is bolted to the motherboard. I do not get freaked when something goes wrong on my PC that I built, as I know what is in there and can swap out a part with a working part from an older computer while a replacement is coming.
I primarily play on PC these days because I have been burned too many times with my 360 (currently on my 3rd and thats about to die as well). I refuse to invest further in the 360 because I can see a future where most 360s are dead and then how am I going to play my games. I am still able to play pc games from the 90s (although a bit of dark magic is necessary for the windows 95 days).
The initial investiment into a gaming PC is quite high though but look at it this way. The cost of your average computer and your games console would be more than enough to buy a good pc and then you can just update it every now and then.
