The great leveler when traveling is the moment we all have to reveal our laptops while going through airport security. Over the years, I’ve been using this annoying ritual as anecdotal research for the types of computers business travelers are really using.

Sometimes the data is skewed, such as when traveling to a Mac conference. Seems likely that I would see more PowerBooks than usual in that situation. But my recent trip to Orlando for PMA was a fair test. This show is for retailers, marketers, photographers, enthusiasts, and guys in suits (who I have no idea what they do). In other words, this is a very diverse crowd.

What I noticed going out and returning home is a higher proportion of sleek Apple laptops in those dull gray plastic trays at security checkpoints. It used to be all black Dells, Toshibas, HPs, IBMs, and various other Windows machines. The trend is changing. Seems as though I’m seeing a much higher ration of aluminum laptops scooting through X-ray machines these days.

Oh, and by the way, my order of putting things through the machine: shoes first, carry on bag second, laptop last. I don’t go through the metal detector until my laptop goes into the X-ray machine, and I’m usually on the other side as it makes it way out behind my other items.
