I use Remote on most of my computers with iTunes installed on. Aside from an expected delay every once in a while, everything works in an instant. Even in the basement where my internet can be a little slow, I can control my Dell OptiPlex 755 connected to Ethernet with most things happening instantly. The only thing I would like to see is an implementation of Remote in Control Center so I dont have to wait for Remote to connect back to my computer, even though the wait is only like a second or two, and so I dont have leave the app Im currently on to change my music through Remote. Though that isnt enough to bring the review down to a four star.
