Amid a slew of incremental improvements to its iPad tablets and MacBook laptops, Apple today announced some landmark news about its oldest surviving operating system: It will not charge for the latest big upgrade, Mac OS X Eighteen years ago, the tech industry's dominant company made nearly half its revenue selling OS licenses. Now, as Apple just confirmed, the prices of OS licenses are headed towards zilch. Microsoft — the king of the operating system in the '80s and '90s and on into the aughts — still charges PC makers who sell the Windows OS preloaded on their desktop and laptop machines, but that business is shrinking, thanks in large part to the continued success of Apple.
OmniGraffle—for diagramming, flow charting, and wireframing, and OmniGraphSketcher—for plotting and visualizing data. The first app I tried out was OmniGraffle. Like its desktop counterpart , the app aims to help you express your ideas visually. Translating all of the diagramming depth of the Mac software to the iPad requires rethinking some key interface elements, and Omni did so quite cleverly. When you first launch OmniGraffle on the iPad, you should take time to go through the brief tutorial document preloaded in the app. While many of the touchscreen interface elements in OmniGraffle will quickly if not immediately feel intuitive, some of the design decisions are less obvious. The tutorial does a good job of explaining those.
