I'm not a native speaker but my guess is: a potato is a vegetable (literally) and so is a couch potato(in the figurative sense - someone who "vegetates" in front of the telly)etmum said:
<A mouse potato is the computer equivalent of television's couch potato: someone who tends to spend a great deal of leisure time in front of the computer in much the same way the couch potato does in front of the television. Both activities tend to be accompanied by snacking. A recent survey by the American Snack Food Association found that 85% of Web surfers snack at the computer. It has been observed that this habitual nibbling and relative inactivity can lead to development of a characteristic potato-like body form.>etmum said:

Do I *have* to choose between being a mouse potato and a couch potato? Is that all my 'life' would be if I used Windows 98?
couch potato slang (orig. U.S.)
potato app. punningly after (boob-)tuber = television addict and vegetable tuber, but perh. simply by association with VEGETABLE n, a person who spends leisure time passively or idly sitting around, esp. watching television or videotapes.
