It is an Adesso PCK-308UB. There is also one that uses a PS/2 plug, but I want this one so I can use it with my laptop if I need it. From what I have read, it is basically like a touchpad on a laptop so you don't need a mouse. I probably would not use it for regular web surfing or anything, mainly just for mousing while transcribing.
