When the Mac is less than 10% of their revenue, why should they bother to care? They can coast on their reputation and they have a captive audience of iOS developers who will buy any Mac because they have to.
And I don't say all of this lightly. I've read the threads the occur after every major Apple release. They're always replete with naysayers. I've never been one of those people. This seems different.
Has any company ever said that they didn't care?
