I would lean toward a consumable of some sort. I think having to rewind a cord or hose after each use would be a fairly large pain, considering it doesn't have any handles or rewind springs. Not saying they couldn't be added, but as is, not ideal for that.
Do you use any large quantities of tubing, wire, or rope? I would think a rope dispensary would be kind of neat. May not get used much, but it would be handy to spool off a length of rope just right for a job.
