In two days Apple will release a new version of its Mac operating system, so last Saturday I watched the guided tour and read about all of the 300 new features of “Leopard.”

I thought my strong interest in the new operating system was justified since I’m going to take the opportunity to replace my 4½ year old Titanium Powerbook with a new Leopard-powered notebook. But then I got thinking, it’s just a tool. Using a Mac isn’t my goal per se. I might as well get exciting about all the tools at Home Depot — and I do — but if I don’t build anything with them, they’re useless.

Jon Udell refers to himself as a “toolsmith” — someone who loves the tools of his trade — and I think I have a bit of that in me. Being a toolsmith means knowing the ins and outs of one’s tools, with the potential to be very productive with them. But Merlin Mann warns against continual “fiddling” with tools and systems and methods at the expense of just Getting Things Done.

Use whatever tools work best for you, but use tools to build something.
