I have both the Xbox and PS3 and I must say the PS3 cost me more..... I say like £100 more.

Xbox 360 20gb got in 2007 for £200 and PS3 got in 2008 for £300.  I don't understand the arguments about costs, I see only what I see... that the PS3 now costs £170 more to buy in UK shops.

You really shouldn't add the WiFi option as part of the mandatory cost. Internet capable is provided.

Also while I agree requiring to pay for repairs down the road is a pain in the butt. You are stating it's only 30% of current consoles. Which means you may not end up paying it at all. So you are tacking on $200-$230 just for justification reasons. If this was a solid guarantee MUST pay then I would agree with you, but it isn't. I have a feeling that you didn't deliberate for very long. I'm sure you looked at the features and some possible cost difference, but were all ready leaning towards the PS3 already. As I'm saying the reasons you give seem more like self justifications of your "right" decision.
