Happy Groundhog Day from Sonny, Cher, and your slowly expiring SWAG board of directors.
Macworld magazine informs us that there are new versions of the Apple operating systems available. These are bug-fix releases Mac OS X 10.10.2 (Yosemite) for your Mac desktop and laptop computers and iOS 8.1.3 for your handheld devices: iPad, iPhone, and iPod Touch. Since these aren't major releases, there's no real reason other than sloth and indolence to hold off upgrading.
Get the OS X upgrades from the App Store; get the iOS upgrades by tapping Settings > Software Update.
