So I'm having thoughts

About whether I should get a PS3 or not.
Now I love my Xbox 360 and it's a great system to play.  I also own a Wii and it's a pretty good system, although my little bro mostly uses it, I love playing RE4 and Mario Kart Wii on there.
But I just feel like getting a PS3 just so that I don't have to worry about which system is better.  I just thought of getting a PS3 just so I can enjoy all types of games and not worry about which console is better and what not.  There are also some games I enjoy on PS3 like MGS4 and Mod Nation Racers was cool too.
This isn't a for sure thing though.  I still need a job if I even want to go as far as to get another console.
But anyways, hearing some people's opinions, some say it's worth it, others (who also own a 360) say they rarely use it.
So people that are neutral and multi-platform I ask you this: Is the PS3 worth purchasing if you own an Xbox 360 already??
Like I said, it's not a for sure thing, but just letting you guys know it's something I'm keeping in mind.
And no fanboyish comments either please.  I don't want any XBOX 360 RULZ, PS3 SUX or FUCK 360 or any of that stuff.  Please don't post those type of comments.


Which Left 4 Dead game do you like better and why?

I prefer the original Left 4 Dead myself.
I just prefer the darker setting of the original.  The 2nd one was a good game but it was too much daylight for a game like Left 4 Dead imo.  The first one had more suspense because of how majority of the levels were in the nighttime. 
Which one do you prefer?


Games/DLC/etc. that I want to get over the summer

Left 4 Dead (my friends been wanting me to get it for a long time)
