Issues not universal
Some users of the new iOS iWork apps are experiencing "blue screen of death" crashes, complaints indicate. The crashes can potentially affect Pages, Numbers, and Keynote alike, and are easy to trigger. After launching one of the apps, users just have to open an existing document and then hit a device's Home button. This may not only kill the app, but force the device itself to reboot. Not all users are suffering from the problem however.
Apple recently made the apps free, presumably to compete with the number of similar apps already available on the App Store, and on other platforms, namely Google's web and Android offerings. Shortly after Apple's iWork announcement, Google made its own QuickOffice free.
