It's hard to imagine someone using an item like this more than once, but the "Push Button USB Webkey" apparently isn't intended for everyday use. It's basically a keychain-giveaway type of promotional tchotchke that has just one purpose, to open up a specific Web page when pressed.
The button does include a couple of USB ports, according to Red Ferret, perhaps to encourage its presence on the desktop, rather than being tossed after the first click. The competition has gotten tougher, however, with more useful freebies like and even becoming more common.
Something like the Web button might have been a bit more popular in, say, 1998.
