I have a wide screen monitor on a stand with room to slide my laptop computer under the stand. I have a wireless keyboard and a wireless trackball mouse. I also have a little connector thing so that I can watch regular TV on it (or whatever we have recorded) using Windows Media Center. Or I can watch Netflix, Google, Amazon.
It's also a necessity to have the computer in the room to use the Silhouette (or Cricut, although I haven't used that in a long time). I have a wireless printer/scanner/copier in the room too.
