You're right about these. I think the distinction I should have made was about how much effort they put into the different products. I think the three you mention have not have a ton of Apple's resources put into them like their other products. If they're going to actually produce a car from soup to nuts, there is no real way to half-ass that like they have the TV.
That was an inclusive "and". I think that by "slow and methodical", the author was going for the tank approach rather than just slow like a slug, which doesn't do much good.
Depends on how you look at it:
- They've been fairly slow to enter the TV market.
- Homekit is out there but hasn't received a lot of attention in recent keynotes.
- Healthkit and related medical technology isn't something they have been extremely quick on.
