Query: Junk that won't work and Isn't Supported by HP

If you like ordering something, only to return it because it won't work, isn't supported, and commitments made to you by a Support Center to have someone call you back with a fix for a known problem are ignored, you'll love the HP Wireless Printing Upgrade Kit. I don't know if it works with Windows XP but I do know that trying to make it work as advertised with Vista isn't possible. I've made a promise to myself to never buy another HP product.
