Some manufacturers love the mouse as a marketing gimmick. And it’s indeed nice for graphics. If you’re a writer or secretary, however, and if you lack three hands, you may be better off mouseless. Why? See Backup [X], “Of Mice and Men.”

I’ll also try some candor on another touchy topic—computer crime.

In Chapter 10, “Jewels that Blip,” you’ll learn how to protect your company secrets inside your computer and how to prevent the machines from suffering amnesia and destroying electronic records. Although electronic Willie Suttons exist, your real worries are often mundane. This book won’t keep you from spilling coffee on a floppy disk, but it will tell how, using good software and good habits, you can help ward off both crooks and accidents.

Much of Chapter 10 is about larger computers, and quite logically so. Increasingly, your micros will be talking to mainframes, as the big machines are called, and your facts are only as safe as the electronic repositories where you store them.

Computer security will particularly matter in the era of telecommuting, a subject covered in Chapter 11, “Wired to Work,” which will show you how “electronic cottages” often can be both productive and humane.

A California professor says by 1990 as many as 10 million U.S. workers could be tapping away on keyboards at home. In Chapter 11, you’ll learn how you may be able to “telecommute” within weeks or months if (1) your boss and company are sympathetic and (2) your office politics permit you to do so without harming your career. Why wait for official telecommuting programs from corporate headquarters? Chapter 11 advocates nothing less than a grass-roots telecommuting movement by corporate writers, programmers, salespeople, and working mothers. Toting up the savings that telecommuting can yield, more and more corporations will encourage experiments. Many people—though not all—thrive on it.

“It seems foolish for me to get in a car to go to an office,” said a Washington-area telecommuter, “if I can go to that office by phone.” Without the wear and tear of rush-hour driving he became more productive.

You needn’t telecommute every day. The chapter, in fact, starts with the example of the rush-hour hater who made it a point to keep up with the office crowd in person on occasion.

Chapter 12, “How I Found ‘God’ on MCI (and a Few Other Odds and Ends about Electronic Mail),” tells more about sending computer messages over the phone lines. Some E-mail nets even link up with the old Telex networks. During the writing of this book I corresponded via computer with people ranging from William F. Buckley, Jr., to Captain Zap and the MCI mail-Telex connection transmitted last-minute changes to my publisher.

In Chapter 13, “Net Gain$,” you’ll learn how different computers in your own office can share the same programs and exchange information without people constantly having to carry floppy disks from one desk to another. A Michigan company may be enjoying as much as DLR $1,000 a year more in effective work time from each staffer as a result of its internal computer net.
