I love my Vitamix blender, but do not like using a plastic container.  It is not good for the environment and is easily damaged.  Plus, Vitamix just charges way too much for it.  It is nice to have the lower profile, wider container, rather than the taller one. 
 When this machine bites the dust, I will be moving on to another brand.  (Of course, if Vitamix decides to switch to glass and make their products more reasonably priced, they will have me for life.)
