Some other points to note
Velcro has a limited life span, and loses its stickiness over time. However, it is the fuzzier "loop" material that wears out, while the "hook" side lasts indefinitely. With this in mind, you will probably want to attach a tab of hook Velcro to your Palm unit, and use the tabs of loop Velcro on your shirts. (This is assuming you change your shirts more often than you change your Palm unit.) It's also possible to buy hook and loop closures in different colors, should you want to go all out and coordinate the colors of the fasteners to the colors of your shirts.

You may want to attach the tab of Velcro to the inside surface of your pocket -- that is, the side closest to your body, rather than the to outer flap of the pocket. If you attach it to the outer layer of fabric, there will be a slight imprint of the Velcro tab on the outside of your shirt. However, with the Velcro placed this way, it will be a little more difficult to make sure the tab on your Palm device is contacting the tab on your shirt. Therefore you should use a longer strip of Velcro, perhaps 1/2 inch by 2 inches, on the inside of your shirt.

There you have it: a combination fashion tip and safe-computing (Palm device style) tip for Palm Connected Organizer users that may be the most important and money-saving safety tip you'll read anywhere!

Karl Bunker is a Macintosh software developer living in Brookline, MA, with a dog, a cat, a wife and a securely Velcroed Palm III that regularly beats him at PocketChess. You can visit his Web site at http://www.IronSoftware.com. There's no software for Palm devices there yet, but Mr. Bunker promises that he's studying his PalmOS programming manuals, and hopes to move into Palm development soon.
