I like and own both systems, but right now I am leaning towards the PS3. One of the best things (though removed) was being able to put linux on my PS3. Now that it's gone though I still love the fact that I pay for nothing, have a kickass web-browser, and a solid line-up of sony-only games. Now that I have my vita the functionality of my ps3 has been boosted due to the plug n' play feature.

360 is a solid machine with a nice library of games, but it doesn't give you as many features as a PS3 does. In the long run you even end up paying more for it than a PS3. Regardless they both rock.

By the way I suggest you guys get a Vita, it's pretty nice.
Oh and another note, just because the PSN got hacked doesn't mean it's bad. If a hacker, or hackers wants something bad enough then by all means they'll probably be able to get it.
