One reason I'll never sell Apple is that it's hugely desirable for the younger generation. I'm staying in a developing country and if you want to be "cool", you must have an iPhone. In the US, something crazy like 90% of teens uses an iPhone. This means the younger generation will be buying Apple Watches, Macs, iPads, and subscribing to Apple services in the future. Tomorrow's young adults will be more attached to Apple than today's adult generation.
Statistics also show this trend. iPhone surpassed Android market share in the US after a decade of being the distant second. Macs are growing while PCs are shrinking.
