This time around, Apple is shaking up several industries with changes and additions to its hardware and software.
Like the MacBook Air, the MacBook Pro will no longer come with a DVD drive. Apple will sell a USB optical drive in case of emergency, though.
Apple ditched hard disk drives in favour of the faster, cooler, and quieter solid state drives. They're more expensive for now, but that will change.
iCloud now syncs Pages, Numbers, Keynotes, Messages, Reminders, and Notes. Syncing works out of the apps, not some standalone file system.
Now that Apple's own Notes app syncs to iCloud, you probably don't need apps like Evernote for basic note-taking.
Apple's Maps app now offers turn-by-turn directions that it gives aloud. And soon, car companies will put a Siri button on their steering wheels. This is bad news for Garmin.
iOS 6's Guided Access feature thwarts distractions by limiting use to a single app. This means apps like Isolator, which puts a black background behind the app you're working in, are unnecessary. Guided Access will also help autistic children stay on task.
The new version of the iCloud will automatically sync Reminders across all of your Apple devices. That means Wunderlist is no longer necessary.
Mountain Lion's new Gatekeeper feature gives you control over what types of apps get installed. Even though OS X never really had a virus problem, this seems to be the final nail in the coffin.
FaceTime now works over your cell network, so you don't need Wi-Fi anymore. This is bad news for apps that in the past were the only way to do that. Tango down.
Messages, Mountain Lion's new instant message app, lets you use all of your IM services--AIM, Google Talk, Jabber, etc.--at once. It also lets you send iMessages to iOS devices. Adium is out.
