Um.
Okay...
Bar the Xbox 360 (which has terrible build quality) all consoles are reliable.
Plus, those so-called 'spoilt' rich kid's that you're talking about are usually chavs and teenagers who can't afford a £1K PC.
And I don't know what you mean about us pushing the technology further. The PS3 uses the Cell CPU, developed by IBM, which has nothing to do with the Enthusiast Gaming market and, technology-wise, the Cell is ahead of anything us PC users have. 8-cores on one CPU? In a console costing around £300? I'd say that was pretty amazing.
Best we have are Dual CPU 8-core £1500 Mac Pro's (or the PC equivalent, which is usually similarly priced).
PC gaming is not dead, and probably never will be. But console gaming is what pushes software forward.
All PS3 & Xbox 360 games are multi-threaded, for example.
