Do you mean functionality? I understand usability to mean "ease of use", and in which case out of tablets, consoles and PC, PC is by far the worst by a significant margin.
Yeah, meant 'functionality, I skimmed through and thought I saw something on people doing homework/document editing on tablets etc and not needing PCs - but maybe that was another thread lol.
It's self-evident that PCs are more usable for anything other than basic web browsing/doc editing. The main advantage tablets/phones/consoles have is the convenience of not having to go to your PC.
Whether PCs offer a gaming usability experience the equal to consoles simplicity yet.
Although it changed into considering a theory that people in their 40s have a natural aversion to change that comes with the species and growing older, especially the idea of trying PC again (despite contributors in this thread making the usability comparison with their own current real-life use of PCs for gaming). This argument came to a head when the evidence of older (40s) people's resistance to change is that more older people own iPhones, proving that the under 30s are dynamic and courageous enough to embrace the exciting, risky world of Android. The cost of iPhones versus Android and the limited income of minors clearly doesn't enter into it.
I think such strong arguments shut the rest of us up, and now I'm going to go do what I've always done and not do anything new because I'm too old for change. Except if what I always did was build and game on PCs in the 90s and then moved on, because I'm too old and set in my ways to do what I used to do. So I'm going to game on consoles because PCs are old news and I won't reconsider them because I'm too old and though I've owned consoles for a far smaller portion of my life, that's apparently what I'll be sticking to forever more. Until consoles die as a concept. Then I guess I'll watch TV, because using a streaming service or gaming PC or gaming tablet will be too new and scary.
Lol...poor Shifty
While I'm pretty sure people generally get more conservative as they age and there is literature to that effect,
I don't know how you can get from that, to positing that someone with your technical nous suddenly becomes averse to doing something they've done for ages (buliding and gaming on PCs) because of this correlation between age and conservatism - you'd think that you would become more averse to switching to console if anything.
...
As for myself, I don't game on PCs anymore as historically it was always more of a hassle to set them up and get games working (this is in the late 90s/early 00s) especially if you didn't have a high end machine. When you did get the game working, I always found myself endlessly fiddling with the settings to get the ideal balance between performance and graphics (more choice is definitely not always a good thing). And then being the nature of the beast (and probably related to having middle of the road hardware) you would always encounter a crash at least every 10 hours of playtime - either because of some bug, loading a new area/ coming across a demanding gameplay section, trying to switch to desktop etc.
So moving to my Xbox in 2002 was pretty damned great as you could play a game like Halo and not have to worry about the latest version of Direct X, updating your graphics cards drivers, low framerates/crashing etc. And I haven't looked back since.
As a result, I don't even have a desktop PC anymore, I first moved to a Dell XPS laptop and now have a 15" rMBP, both are pretty capable as gaming laptops but I don't like gaming on them (aside from the occasional, undemanding indie title on Steam where I can use the integrated GPU) as they make a lot of noise and heat when the CPU/GPU are being stressed - which I find unpleasant (I am the guy who gets irritated by the blinking LED on a portable HDD when watching content from it in a darkened room lol).
I can readily concede that with the advent of Steam and the newer versions of Windows, PC gaming has got a lot more user friendly than 10-20 years ago but since consoles are good enough for all my gaming needs I don't see the need to get a gaming PC. It's like how iPad sales are tailing off, for most people their iPad 3 or whatever is perfectly adept at what they need it to do and so why should they upgrade to an Air 2 for slightly better graphics and performance.
For most people 'good enough' is the enemy of 'the best' and the lack of drastically better graphics or unique gameplay experiences only available on PC is I think the most salient reason why consoles are favored these days.
Remember that 20 or even 10-15 years ago you could get gaming experiences unique to PC (for one, RTSs were all the rage, you had must-play exclusives like Half-Life 2, and there was no online multiplayer to rival the likes of Counterstrike or Battlefield) - this isn't the case anymore so PCs have been relegated to 'more of the same' status like the Air 2 vs earlier iPads.
Interestingly though, the only thing I miss about PC gaming is strategy games - I used to play a lot of StarCraft, Warcraft, Civilization, Age of Empires/Mythology, C&C, city-building sims back in the day but not anymore (I tried the Starcraft 2 demo on my Mac but the fan noise turned me off getting the full game). But, I have nowhere near as much time as I used to, to play games so maybe that's a good thing. Strategy as a genre has also got much more niche these days also.
