First available for iOS on the iPad, Apple's iWorks apps were released on Tuesday for the iPhone. The price is the same: $9.99 each for Pages (word processing), Numbers (spreadsheet), and Keynote (presentation software). If you already own them for the iPad, they are a free upgrade for your iPhone. The question is how practical it is to do these things on the small screen of an iPhone. You can read one person's experience in a review on the PC World website. Bottom line: fine in a pinch, but don't expect to use the apps regularly in your business.
