Intel has attempted brand awareness for years with its "Intel Inside" campaign. Stickers, ads, leaflets... They do strong comarketing campaigns with PC OEMs to make sure their brand is somewhat pushed to end customers. In the most unscientific statistic ever, my mother knows what Intel is, but never heard of ARM. The bad news for Intel is that nobody ever is saying "does this device have Intel? If not I'm reluctant to buy", which is possibly what they were aiming at.
It does matter to them, though, because if the computing market turns towards ARM tablets (tablets seem to be what Microsoft is pushing), and they get one without realizing it, they won't be able to run any of the stuff they used to be able to on Windows. Windows has a long history of backwards compatibility and if ARM becomes dominant, it will end up being pretty much pointless. CPU architecture isn't a huge difference when they are compatible, but this time it is a big deal.
Still, it's not something the GenPop will know or care about. From their POV, it's a product issue - this tablet does or does not run some software. It's easy to paper over 99% of those differences by... writing new software. I mean, people don't complain that iPad doesn't run vanilla MS Office.
Which boils down to the old "consumers view computers as black boxes" argument. The question is whether we should care about that or not, and whether the pain of not being able to run GenPop's favorite software grows too big. Being locked into the respective device's app store hides that pain to a degree. And whenever it becomes noticable, GenPop rather considers switching to a different vendor than considering the tech in question. As long as people put band-aids around the architecture, I'm not sure why any consumer would want care about the underlying hardware in question.
Thats because the computer as a mix of hardware and software is something fairly new. The home/personal computer didn't really happen until the 80s. Before then every device had a defined purpose, and if there was any software it was living as "firmware" inside the hardware.
Damn it, i still recall when people got hot and bothered about getting updates for their Nokia Series 40 phones over the air. Before than you only got it done if it was obviously broken, and to do so you brought it to the service desk of a nearby store or some such.
Personally I like using my Windows laptop-tablet hybrid for old games from GoG, and I'm sure a fair amount of other people run old programs that aren't going to be updated for new architectures on these.
