Of course, when "free online" comes at the cost of security (and by extension having it taken offline for 24 days), the lack of fair/similar promotions when compared to its rivals [http://www.slashgear.com/eas-mass-effect-3-online-multiplayer-events-barred-on-ps3-15222970/], so-called "firmware patches" that don't seem to fix the complaints that players have, thirteen-hour maintenance times [http://www.pcmag.com/article2/0,2817,2403064,00.asp], continuously gets content weeks after the 360, and that it's on individual game developer's to incorporate their own VOIP due to a hardware limitation, I'd say I'm pretty damn glad I didn't get one.
I'm a logical guy, and the logic didn't match up for me to buy a PS3. (Granted, a lot of things have changed since I went hunting for my first "next-gen" console)
For starters, you couldn't choose whether or not you wanted the Blu-Ray drive, which drove the cost up for me because I was not interested in Blu-Ray movies.
The other issue I have is the insane PS3 controller. For starters, I take great issue with the use of pressure-sensitive tactile buttons where the range-of-motion of a trigger is far more useful. Gran Turismo 5 (which was the disappointment of a lifetime for me seeing how much I adored GT2 for the PSX) decides to use the "X" button for acceleration instead of the full range of motion provided by the trigger. In a realistic racing game, you need throttle control, and no matter how pressure-sensitive the buttons are, a trigger is simply better. I also much rather prefer the trigger setup for FPS games, tapping a button to shoot seems strange to me (I assume most games let you change this now, but the PS3 version of Battlefield 3 that I played seemed to use R1/L1 as Aim/Shoot). All in all, if all of that is indeed fixable, I just can't understand how anyone would find the PS3 controller comfortable. The 360 controller contours to my hand and is comfortable to hold for long periods of time.
The other issue for me is reliability. One of my best buds from high school bought a PS3 soon after I purchased a 360 almost 5 years ago (The original 120 GB Elite, if anyone remembers), and paid $200 more than I did. In the past 5 years, that thing has made 7 trips to various servicing centers, consistently encountering what PS3 users know to be the Yellow Light of Death (Not sure what this is, but it was a real problem, whatever it was) whereas my 360 has run strong (and loud, to be fair) without any issues. The closest thing I've had to an issue with it (and I use it for LONG amounts of time, mind you) is from my own stupidity; in my frustration to plug in a USB keyboard, I bent the front port's pins, and because one of the pins was touching the metal of the console, its failsafe kicked in and prevented itself from booting to avoid a short. After using tweezers to remove the offending part, everything was just fine.
I love my 360. I don't know what issues others seem to have with the console, but if you treat it properly, clean it out every so often, never touch it while a disk is spinning, and make sure it's well ventilated, it will treat you well.
