After dealing with HP customer service and FedEx all day..
I finally got my order squared away (IE they were able to find my supposedly "shipped" touchpad.. anyway) and at the end of the conversation the representative asked me if I would be interested in reserving any touchpads for the coming week. Of course I responded with "Why yes I would."
I was told that I could reserve up to 10 Touchpads and be notified within a week or so when they become available. For those of you who missed out on this first sale, get on HP's list ASAP
