How is a company like Amazon able to constantly funnel cash back into their company while Apple's reserves just grow? Do you think it's the nature of the business (small margins for Amazon, giant for Apple) or different company priorities?
Amazon on the other hand continues to build out enormous infrastructure both for Amazon Web Services and Amazon.com. AWS is also in something of a price was with Google right now with various headlines today somewhat hyperbolically predicting that cloud services were headed towards essentially free. That said, Amazon is arguably building a huge (and costly) moat around its business.
They're both impressive companies. But Apple's business requires a whole lot less reinvestment relative to revenue both now or in any near- to mid-term foreseeable future.
