Jing Project is a free tool for both Mac and Windows users, that lets you capture your computer screen as a static image or a screencast, and then share your screen capture as a URL. Which means that not only are they providing the software to create the capture, they are also providing free hosting. How could you use this? It’s up to you. Add your Jing captures to your chats, your social networking, or your websites. Use to for fun, or to demonstrate computer stuff to friends and co-workers.

Mac users with Intel-based machines have several options when it comes to running Windows on their Leopard machines: Boot Camp, Parallels, or VMWare Fusion. Boot Camp is included with OS X, and provides a dual boot machine that runs either OS, but only one at a time. Parallels and VMWare are virtualization products that allow you to run both operating systems simultaneously, in different windows on the Mac desktop. For more details, read Sam at NotebookReview .

There are a variety of ways to convert an iPod from Windows to Mac, depending on how much metadata (such as playlists, album art, ratings, and date added) you want moved, and how your Windows iTunes library is configured. To transfer with CDs or DVDs, use iTunes Backup. To transfer a lot of music quickly (but not the metadata) try this technique from Cnet.com. Or, to use the iPod itself as a transfer hard drive, with these instructions from Apple.
