View Single Post do you assign it a context?

For example, I've got tasks that
  • can only be done on my laptop
  • can only be done on my iPad
  • can be done on either

What do you do with that third category? The only thing I can think to do is create a third "Laptop or iPad" context, but something about that rubs me the wrong way. Is that the only solution? Any suggestions? Thanks!
