Business users will be pleased to know that Exchange is now built-in, and is able to synchronize with integrated Mail and Contact apps from Apple. This ought to bode well for Mac users since it will open up a whole new market for users who want to use Macs for their everyday work but previously couldn’t due to the gap in between which has now been bridged. Most people who are averse to Outlook would prefer to reap the benefits of Exchange within a Mac environment. Snow Leopard’s presentation is finally over, and it will retail for $29 (single license) in order to encourage as many users to upgrade as possible. The family pack is going for $49 (5-seat) when both versions are released this September (Developer Preview is out today).
