Should I Trade in My Xbox 360 and Purchase a Playstation 3?

I currently have a 360, but I sometimes feel disappointed by the system. I had both Playstation 1 & 2 but I decided to buy a 360 when both were launched because of price. I really want to play DC Universe Online, but my computer isn't fast enough to play games and buying a PS3 is cheaper than buying a new gaming computer.

The only 360 exclusive I actually played was Saints Row, but they made ports for PS3 now and I don't play Halo, Mass Effect, Gears, Left for Dead, etc. so it wouldn't make me lose sleep if I could not play those games.

I liked God of War on PS2 and have played some games at friends houses like Killzone, Infamous, Gran Turismo, and I miss playing MLB: The Show.

A lot of games I like are multi-platform and I'm not a big online guy so I hate spending money for online and I hardly even play.

Could you guys help me out and don't just say Xbox rules, PS3 sucks. I need reasons and I don't want to make a mistake.

Suggestion:

You can consider buying PS3 slim
Ps3 Pros:
1) Quiet
2) Motion sensitive controllers
3) You can use any Bluetooth headset, keyboard, mouse, etc….
4) Blu-ray
5) Lack of flashing lights on front of machine!
6) Built in wi-fi card
7) HDMI included
Free Online Community and Game Play
9) Tech support speaks english and appears to be located in America, they understood my name and my question.
10) Controllers come with built in rechargable battery and can be charged with any usb port.
11) easy to navigate menus
12) No ridiculous power brick, one cord, if you want to take your ps3 with you somewhere you only need the controller, the unit and the power cord.

Ps3 Cons:
1) No IR receiver, you can't use your regular universal remote to control the ps3 you need a bluetooth which means an extra remote.
2) Shape, this one sounds stupid, but the rounded shape of the ps3 really annoys me because you can't stack, say your wii, or even lay your remotes on top of the unit. (maybe you shouldn't do that anyhow LOL)
3) Less games, or at this point I guess the better point would be less games made for the ps3, instead of built for the xbox and ported to the ps3, this is however changing and in the future will be less of an issue.

you can buy easily this online:
PlayStation 3
