No one is questioning (at least I'm not), the profitability of the iPhone. Its making Apple gobs of money.
No, I think some of the comments are on point. When a company relies on a single product for most of its profit, its akin to putting all of your eggs in a single basket. if something bad happens to that single product, then Apple is in a world of hurt. No company can easily weather a massive drop in revenue, and right now, the iPhone represents 65% of Apple revenue. I'm not saying Apple is doomed, but they need to diversify their product mix. They haven't been sitting on their hands, they've been working on that, but so far, nothing has come close to evening out the product mix and the revenue it produces.
Like others have said... the iPhone overshadows Apple's other operations. It's simply a monster.
It's kinda hard to "compete" with yourself when one of your products is making $32 BILLION in revenue over a three month period.
But Apple tries anyway. Here is the revenue from Apple's products... in BILLIONS per quarter:
$32 billion: iPhone
$6 billion: Services
$5 billion: Mac
$4.5 billion: iPad
$2 billion: Other
I don't know what you want them to do. They sell an obscene amount of phones... you can't fault them for that.
A company like ASUS sells roughly the same number of computers as Apple sells Macs... but I'm pretty sure ASUS isn't pulling in $5 billion in three months selling computers.
The Mac by itself would still be a Fortune 500 company. So that's a huge product... just not as big as the iPhone. Smartphones sell in much higher volume than computers... so it's no surprise that Apple makes more revenue from iPhones than Macs.
Apple is diversified... they just have one monster revenue product and a bunch of other huge revenue products.
Some companies don't even have a single medium-sized revenue product... let alone multiples.
