Interesting Stuff

Developer preview today. Release this summer.

Major new features:

• iCloud, with an iOS-style easy signup process upon first turning on a new Mac or first logging into a new user account. Mountain Lion wants you to have an iCloud account.
• iCloud document storage, and the biggest change to Open and Save dialog boxes in the 28-year history of the Mac. Mac App Store apps effectively have two modes for opening/saving documents: iCloud or the traditional local hierarchical file system. The traditional way is mostly unchanged from Lion (and, really, from all previous versions of Mac OS X). The iCloud way is visually distinctive: it looks like the iPad springboard — linen background, iOS-style one-level-only drag-one-on-top-of-another-to-create-one “folders”. It’s not a replacement of traditional Mac file management and organization. It’s a radically simplified alternative.
• Apps have been renamed for cross-OS consistency. iChat is now Messages; iCal is now Calendar; Address Book is now Contacts. Missing apps have been added: Reminders and Notes look like Mac versions of their iOS counterparts. Now that these apps exist for the Mac, to-dos have been removed from Calendar and notes have been removed from Mail, leaving Calendar to simply handle calendaring and Mail to handle email.
