The Nielsen Norman Group (NN/g), a user experience firm founded by usability gurus Jakob Nielsen and Don Norman, has appraised iOS 7, and the verdict isn’t great. “Early experience with applications redesigned for iOS 7 is fairly negative: several have worse usability than their iOS 6 versions.” In particular, NN/g cites action labels that are indistinguishable from content, the confusing date picker, confusing swipe actions (for example, activating Notification Center when you wanted Spotlight), and the redesign of many icons, of which NN/g said, “Apple has demolished millions of hours of user learning by changing the icons.” However, NN/g said that iOS 7’s design isn’t fatally flawed, and praised how controls are hidden in Safari, global font size controls, and the streamlined Settings app.follow link
Editing iCal Events in Snow Leopard
Snow Leopard makes looking at event details in iCal easier. In the Leopard version of iCal, you had to double-click an event to reveal only some information in a pop-up box; you then needed to click the Edit button (or press Command-E) to edit an item's information. In Snow Leopard, choose Edit > Show Inspector (or press Command-Option-I) to bring up a floating inspector that provides an editable view of any items selected in your calendar.
