Velcro Alternatives?

sniglet999 asks: "I've got a PDA and a Nokia cellphone that can connect to the net. However the IR port on the phone is on the side, and the port on the PDA is on the top. This means I've got to hold the two together, line of site for the connection to work (with increasingly cramping hands, I might add). The idea of mounting velcro to a notepad, so that you could stick the PDA and the phone in the proper position sounds good, but I don't want velcro and it's associated adhesive attached permanently to either expensive device. 3M has some cool hooks that adhere to the wall with a pull strip. Pull the strip and the hook is removed, leaving no residue on the wall. Is there something like this on a velcro backing? Is there another solution? (Short of making and attaching a light pipe. The whole objective behind all of this was to carry less)!" These aren't the "cool hooks" the submittor had in mind, but might these serve as a way of mitigating the problem (since they are self mating, they don't suffer the major problems of velcro). Does anyone else have alternatives to velcro which they use and prefer?
