Anecdotal, i never bought apple products for the reasons mentioned above. I don't like paying premiums for brand names. I'd even pay a premium to not be associated with religious apple fans lol
Having that said, for 4 years i have a macbook. It's not overpriced imo. You have to look at the full package, the invisible time you save by having close to no problems vs permanent bugs on Windows (especially dumb users like myself). The fact that this stuff seems to last forever. It's vague, but it helped me understand what makes customers sticky.
People who say it's overpriced usually look at the hardware. I'm not sure if that's the right way to compare things, but rather how easily you can create the same experience for a lot less. Not that easy to create a competing religion. Reminds me of another guy who wrote yesterday something like "just copy the customer experience from pokerstars"
. Armchair economist lol.
About the value of the stock i have no opinion, not my area of expertise.
