What, no home slushy machine?

I saw this thing on a quick stroll through the mall. I'm sure its existence isn't exactly news, but it is to me.

The outstanding question for me is: why? Why would anyone want to replicate their mini mart hot dog experience at home (or in the office!)?

And are people eating thaaat many hot dogs that they need an entire appliance dedicated to them? If so, these folks would be really happy. There has to be another use...I wonder if it can toast a nice marshmallow?
