Apple's Online Store is currently down in advance of Apple's announcement today. Usually a sign that announced products are available for preorder or purchase at the end of the announcement. Expected today is a refresh of the iPad line with thinner models, the addition of Touch ID fingerprint sensors, new A8 processors as well as updated iOS 8 software. Also widely expected are new iMacs possibly with Retina Displays as well as maybe new Thunderbold displays and Mac minis, two product lines that Apple has left untouched for a long time.
