This is coming from a longtime PC gamer, some reflection on how I've gravitated towards consoles. I am now a "Console player who happens to have a PC". It's not that I've played turncoat, it's just become more cost efficient. I've unconsciously transitioned. No, using a controller instead of a mouse and keyboard is a big difference. I'd rather have my M+K, but I've adapted to the controller and can regularly be in the top 3. I can also still curse obscenely because in a moment of anxiety I overcompensate with the 'sticks' and miss my opponent, who quickly takes me out. In those moments I long for the M+K, but the other 90% of time I'm fine with it. I bought my 360 in 2006 and haven't had to pay anything to upgrade it. My last big PC purchase I bought in 2004 and have upgraded it as much as I can over the years, but it's clearly outdated and I need a whole new rig that I'm not in a position to buy yet.
In this light, it's been easier to rely on the 360 as I'd rather have that than not play at all. I have plans to finally buy a top of the line PC by the end of the year, and I'll start gravitating back to the PC, but in the meantime I have no complaints about the 360. I can get almost any PC game I want for it on there, I just pop it in and play. I also can't complain at all about the multiplayer service on the 360.
Anyway, that's what happened with me. I feel like consoles have just become an easier and cheaper alternative to the PC for a lot of people.
