I only ever owned consoles because they had games that weren't on PC. That's no longer the case for the most part, and all the remaining exclusives tend to be of the AAA blockbuster variety, which is a segment of the market I've completely lost interest in. On top of that I mostly play indies and older games these days, so consoles wouldn't even be an option, really.
I've also never felt like I actually "owned" my digital games on console. Stores for older consoles won't stay up forever, and games can get removed at a moment's notice. The fact that games like Super Mario Maker and LittleBigPlanet are all about letting players create their own levels but then don't give them the option to easily preserve them locally is just nuts. Everything the fans ever made gone, just because they shut down the servers. I've been making my own levels and maps for games since the days of Warcraft II and Doom, and I still have all of them saved, ready to be played at any time on my current PC, so this just seems absolutely insane to me.
Sure, a game could disappear from Steam as well, but on PC there's always a way to get that game back. Hell, in some cases that's even true for MMOs and other multiplayer-only games. I could play Star Wars Galaxies, Warhammer Online or Asheron's Call right now if I wanted to, even though they all got shut down years ago.
