Computers are more and more forming part of a home entertainment system. An Apple Mac mini for example now comes with an HDMI connector and supports native HDTV resolutions. It is often cumbersome to have to deal with a traditional keyboard and mouse in the family room. A great alternative is the Mobile Mouse Pro application. It allows for wireless remote control of a Windows or Mac computer using an iPhone. The application works in tandem with a program that runs on the computer being controlled. It is a great buy for $1.99 at the iTunes store.
The Logitech diNovo mini is also a great alternative if a more traditional medium is preferred. The very compact keyboard and touchpad combination allows for wireless control via Bluetooth of a computer. It folds into a very small clamshell for easy storage. The diNovo mini sells for about $149.
