Usability guru Jakob Nielsen devoted his Alertbox post this week to showing how interfaces can become confusing if elements like buttons and checkboxes are too far away from the objects they act on, using the iPhone app updating interface in iTunes as an example. Our take is that the overall mistake here is that Apple is relying on iTunes for too many unrelated tasks that call out for different interface approaches. follow link
Mac OS X Services in Snow Leopard
Mac OS X Services let one application supply its powers to another; for example, a Grab service helps TextEdit paste a screenshot into a document. Most users either don't know that Services exist, because they're in an obscure hierarchical menu (ApplicationName > Services), or they mostly don't use them because there are so many of them.
Snow Leopard makes it easier for the uninitiated to utilize this feature; only services appropriate to the current context appear. And in addition to the hierarchical menu, services are discoverable as custom contextual menu items - Control-click in a TextEdit document to access the Grab service, for instance.
In addition, the revamped Keyboard preference pane lets you manage services for the first time ever. You can enable and disable them, and even change their keyboard shortcuts.
