I have been using the Jumi app for quite a while and I cannot imagine not having it. My laptop is connected to my 42" LED via HDMI. My iPhone, and/or iPad, become remotes to surf the web, watch movies and TV shows, or just browse my computer.
The only negative, which is why I only gave 4 stars, is that it disconnects from the laptop every time I shut off the screen on my iDevice. If they could write it to always stay connected, even when the iDevice is off, like some other apps I have, I would give it the full 5 stars.
