Is there any reason you would ever get a 2nd console? Like if you have a PS3 would you get an Xbox 360 and if you had a 360 would you get a PS3?

What are the benefits of one over the other especially in terms of games available - both seem to mostly have the same titles to me.

I currently have a 360 but have been thinking about a PS3.

#1 - I haven't gone on Xbox Live because I've tried configuring it but it does not work - it should be simple but apparently not. Also paying $300+ for wireless adaptor (which may or may not work) is waste of money. The Wii setup was plug & place sort of easy. The PS3 would be similar from what I've heard.

#2 - Blu-Ray

#3 - Some game titles that are PS3 exclusive only - but there's not a particular title i really want or can think about

#4 - PS3 games are easier to find here compared to only at 1 shop where we go for 360 games. Only original games required.

And that's about it. So what do you think would it be a waste of money to buy another console just for these reasons?
