chiclet keyboard

chiclet keyboard n.  A keyboard with a small, flat
   rectangular or lozenge-shaped rubber or plastic keys that look like
   pieces of chewing gum.  (Chiclets is the brand name of a variety of
   chewing gum that does in fact resemble the keys of chiclet
   keyboards.)  Used esp. to describe the original IBM PCjr
   keyboard.  Vendors unanimously liked these because they were cheap,
   and a lot of early portable and laptop products got launched using
   them.  Customers rejected the idea with almost equal unanimity, and
   chiclets are not often seen on anything larger than a digital watch
   any more.
