You mean is there a default host for these domains? I doubt it, that's not how domains work. These will be alongside .com .org .gov etc. It's a domain name, not a host name. Expecting to get somewhere when you type ".com" or ".home" into your address bar is like typing "192.168" and expecting to get a "default host" for your local network.
And thus my question about a conventional default. It just seems to me that buying the gTLD will leave users fairly confused.
If you want to access Apple (generically), users will still go to apple.com because even if they know that there's a .apple domain, what's the root host?
My best guess is a conventional default emerges shortly.
Well it's up to whoever runs the root DNS for the domain I guess. But I've never heard of a domain with a default. edit: oh never mind i'm being thick :)
And this isn't necessarily about people wanting to find apple's main website. Apple would have control over all subdomains and hosts in the namespace. They could give a subdomain to every app in the app store. So if you want the Pandora app, you don't navigate to Pandora.com were you might see ads for other mobile devices. https://www.pandora.com/everywhere/mobile You would go to Pandora.apple and only see the iOS mobile app.
