If you're into Numbers, Keynote, and Pages on iOS and/or the Mac, good news — Apple has updated the entire iWork suite to offer password protection for shared documents. That means you can make sure only the person you want to see your document gets to see your document. Keynote for iOS has also gained yet more transitions and... a built in remote. Amazing timing, given that Apple also just killed the long neglected Keynote Remote app for iOS. There are a bunch of other small yet useful updates for Numbers and Pages.
If you're already an iWork users, hit the App Store updates and grab the latest versions. If not, you can get them for free on any new device purchase, or pick them up at retail. Once you've given them a spin let me know — are they as useful to you yet as the previous versions?
