Yes, plenty of people do, including me and most experts. While there is no harm in letting an engine idle for a minute or two, they warm up a lot quicker under even light load. Obviously, you want to keep the rpms as low as possible and really baby-foot it until the temp gauge reads something, but it's the better way to do it. This also begins to warm up the transmission, differential, brakes, etc. They all need to warm up, not just the engine.

If it did hurt anything, you would not be able to see it unless you can see accelerated wear. The book is correct.
