Not really. There's one other major phone OS out there (Android), with the majority of phones made by less than a dozen companies. Linux and Windows are the only other choices when it comes to operating systems for computers, and few companies manufacture high-end laptops with acceptable quality.

The only company selling everything is probably Microsoft, where you can buy a laptop from the manufacturer of the OS. But Windows Phones aren't nearly as well supported when it comes to third party apps, so you'll have to go with Google there.

So there's not really any company (except perhaps Microsoft) that can offer a similar experience as Apple used to.
