Even Macs need a little TLC now and then, and TechTool's reputation combined with mobile convenience makes this a great utility to have on hand.
One of the leaders in Macintosh diagnostic tools has come up with a clever use for old iPods: turning them into mobile help centers. Load TechTool Protogo ($135) onto your Mac and you can then use the software to install customized start-up and repair tools on unused portables. This handy app allows you to create devices that will boot OS 9, OS X, PowerPC, and Intel chip Macs, or even create an exact duplicate of your system, if you have enough room.
A free tech support number (M-F, 12-8 EST) is listed prominently on the manual and our calls were answered quickly and knowledgeably. New users are supposed to get 30 days of support, but we weren't asked registration information when we called.
