I have to say the reason I bought a wii in the first place was because it was so cheap. Yeah I know, I've learnt my lesson and bought a high end gaming PC now, but at the time it was more like "MOM MOM, I WANT A CONSOLE!", "Erm, which one, because we aren't made of money ya know." "YEAH, BUT THE WII IS ONLY £180!!!"..."Let us buy 50 son..."
It was a major selling point. Having a low price is always beneficial, otherwise people wouldn't do it. If I was Sony, I'd have them keep a moderate-high price, but have some sort of package deal, that meant you could get a lower price if you did something beneficial to the company or something. Quite frankly I'm surprised they haven't done something like, BUY OUR TV'S AND GET A 50% DISCOUNT ON THE PS3 or something along those lines...sorta makes sense to me...
