-I'd probably pay $30 for the Airplay feature alone.
-I don't know how Apple thinks they can push these web-enabled apps that only work on their platforms. A chat app that basically only lets you interact with Apple customers is kind of comical.
-Gatekeeper won't win over any Apple critics, but it's actually more flexible/open than what a lot of people feared was coming (ie "App Store apps only").
-Notifications and system-wide share buttons are nice touches. I wonder if the share button will be limited to a few Apple-approved services.
A chat app that basically only lets you interact with Apple customers is kind of comical. – would be. Thankfully you probably know people with AIM, XMPP, or SMS chat identities. And iChat works with those too.
From the official Apple pages: Messages supports iMessage and instant messaging services such as
AIM, Jabber, Google Talk, and Yahoo! Messenger.
Related to this, all my friends and family are already using an Apple product (referring to either iPhone, iPad or a Mac, or all inclusive). Really, everyone I know is. A chat app (and any other) that let me interact with them is perfect.
