Not the healthy ones. Healthy ones have a wide variety of choices, and the competition nipping at your heels keeps user-hating features out of the product. Right now the two smartphone operating systems are being made by two companies who are in court for colluding on hiring. That's the worst possible market, and as you would expect, it produces trash.
One thing I'm looking forward to with my future dumbphones are how disposable they are if they turn out to be horrible.
"Shopping around" among dentists is virtually impossible. I can have only the most superficial and largely useless opinion of a dentist until I actually allow them in my mouth, at which point the deal is done. This is not a "healthy market" comparable to anything we're talking about here.
Ditto laser eye surgery and pretty much anything else remotely medical in nature.
