I’ve been invited to lead an introductory discussion of iOS 8 for members of the Naples MacFriends User Group (NMUG). I’ve been researching and reading print and online articles in preparation for this discussion. Here’s a list of resources you’ll find helpful as you make the decision to upgrade to iOS 8. These websites and articles address features, benefits and concerns regarding this new mobile operating system, including whether to stay with the previous version of Apple’s iOS (iOS 7.1.2) for older devices such as the iPad 2 or iPhone 4S.

Before you update to iOS 8, please read this warning from Tom’s Guide

Finally, there’s iCloud Drive, a cloud storage system that replaces Apple’s current iCloud document syncing, but provides an actual file system, a la Dropbox. Note that iCloud Drive is not supported by the current version of OS X; if you rely on syncing documents or app data with your Mac via iCloud, do not activate iCloud Drive once you’ve updated to iOS 8. OS X Yosemite’s release, coming later this fall, will add support for the new system. Users of Windows machines, or those who only use iOS devices, should be able to activate the feature without any concern.
