8. Podcast Capture
Available on: Mac
Another great feature introduced with Apple's Leopard operating system is Podcast Capture, a utility designed to make podcasting a quick, simple affair--that is, if you also happen to have access to a Mac OS X server running the more robust Podcast Producer software. It's a cool idea, but even Apple's execution hardly serves the needs of the common podcaster, since almost nobody has access to a Mac OS X server. Still, all new Macs come with Garage Band preinstalled, which does an excellent job of creating podcasts using the Mac's built-in hardware.
9. Software Repositories
Available on: Linux, PC-BSD
In a perfect world, you'd never have to leave your chair to find great software for your PC. You'd just pop open a magic software-finding utility and click a few options, and then any application you needed would install itself instantly. That perfect world already exists in Linux, which has long offered software repositories as an easy way for users to find and install new programs.
Linux distributors can do this because nearly all of the software in their repositories is free and open-source; they seldom have to worry about license restrictions hindering their efforts. In the Windows world, however, things are more complicated. A melange of licensing types, ranging from freeware to shareware to trialware and even a little open-source, makes it difficult for anyone to build a reliable software library with the click-it-and-get-it functionality that Linux users take for granted. Until someone builds a massive library of self-installing Windows applications, we'll have to depend on sites such as Download.com, Tucows, and, of course, PC World's Downloads library.
10. Desktop Cube
Available on: Linux, PC-BSD
Some of our favorite OS features aren't so much practical as eye-poppingly cool. Take Linux's Compiz Desktop Effects, for example. We wouldn't say that turning your desktop workspaces into a rotating cube, painting fire across your screen, and making raindrops fall onto your desktop have a lot of mission-critical business value. But that doesn't mean we don't love these features.
Jealous Windows users demanded similar features, and Otaku Software responded. But the Windows version is more modest. Otaku Software's DeskSpace lets you turn your desktop into a four-workspace cube like the one offered in Linux. You can adjust the transparency levels, rotation speed, and mirroring effects, and you can even drag application windows from one side of the cube to another. But that's about the extent of DeskSpace's power. And unlike Compiz, which is free, DeskSpace will set you back $20 after the initial 14-day trial.
11. Application Dock
Available on: Mac
The centerpiece of every Mac desktop is a little utility called the Dock. It's like a launchpad for your most commonly used applications, and you can customize it to hold as many--or as few--programs as you like. Unlike Windows' Start Menu and Taskbar, the Dock is a sleek, uncluttered space where you can quickly access your applications with a single click.
