Both consoles are really unreliable, but consoles always have been ,I had 2 PS1's, 3 PS2's, 2 360's and 3 PS3's
I'm just unlucky, but on the plus side, I only ever needed 1 SNES, 1 N64 and 1 wii, nintendo are built to last
My 360 gets the most time spent on it for gaming as it pretty much always out performs the PS3 in multi platform titles, but for watching blu-ray and streaming from the pc I use the ps3, the 360 is just as good at streaming (even better picture quality on a lot of movies) but I have an old one so it is a tad noisy,
