I would likely never abandon Sony, their products have been very reliable for me. Only had to buy 1 ps1 and 2 ps2s (bought a slim but not because the original broke or anything), 1 ps3, have owned 2 of their tvs in the past 9 years. For me they are solid electronics and gaming goodness.
I despise MS the company for several reasons personally and call me a fanboy or whatever but I won't own one of their consoles ever. My next computer is probably going to be Mac but need to finish my Master's degree up first to have the spare change.
I would consider adding a Nintendo console back into my home alongside my PS3 or PS4 when it hits if they move to HD and something intangible changes (for example I cannot stand the Wii lol).
