+1 on the Canon color laser for home use and drug store / Kinkos / Whatever for printing pictures I want to frame.

That said, I've preferred Canon printers because their scanners are better quality than Brother and don't have as much restrictions as HP.

But the big decision is how much you want to spend on laser toner. If you're not particularly fussy about print quality, you can go with cheap 3rd party toners (~$50 for the 4 color set). They'll work, but it is really a crap shoot as to how good a cheap toner is; when one is "bad", it can leave streaks or some random spots on your printout. This is NOT the printer, it is the toner cartridge. If quality is important to you, the manufacturer brands tend to be top notch. For comparison, a 4-color set for my Canon MF644CDw is about $390 on Amazon (054H set) compared to 3rd party which runs $50-70. But the quality is consistent versus the gamble with 3rd party brands.

If it is about your kids printing out 20 pictures of their cat, go 3rd party.

Maybe there is a cutoff date, but one of the presumed triggers of Alzheimers is stress and to someone who didn't grow up playing with digital electronics, Smartphones are the worst thing.

I knew someone who was in their early 70s and was talked into going from a semi-smartphone to an iPhone. Couldn't wrap his head around it. Sure, he could make calls and text but it was visibly "work" for him and obviously wasn't intuitive; pocket dials, accidental texts, emails as texts and vise-versa, things like that. Now add in that most everyone and most everything practically requires you to have a smartphone to do anything these days, and you're forcing a level of non-intuitive stress on people like him.

He had some minor surgery that needed to get done which wouldn't have normally been a big deal, but I'm convinced that it combined with the daily stress he was experiencing with having to use a smartphone flipped the switch and he died within two years from complications related to Alzheimers.

So I'm sure it is probably measuring people in the 50-65 range, but the people 70+ weren't "wired that way" and struggle with technology as it is. From the few people I've known who got dementia, it was stress related.

So will they retroactively path Airplay to run over Bluetooth even in older vehicles?

It isn't the phone that won't AirPlay, it is the car. Only until the last model year or two of automobiles have we seen wireless AirPlay, as far as I can tell. If you have an older car that only supports wired AirPlay, there are dongles you can plug into the car for ~$35 which will do the trick.
