“Air Mouse” is one of the iPhone applications that is genuinely useful- not a quicker or easier or different way of doing something you already do, but something that lets you do something that you couldn’t do without it. It let’s you use your iPhone as a mouse and keyboard for your PC or Mac- either using the accelerometer as an “air mouse”, or as a laptop-style trackpad.

As I’ve got a PC connected to my TV, this is ideal for me; my iPhone has now become my remote control. Rather than a bulky media centre keyboard or an expensive air mouse (for around £100, last time I looked- the Logitech DiNovo Mini looked like the best option), my phone now controls my computer. No more need for a bulky keyboard or a surface to use a mouse on- I can use my computer from the comfort of the sofa. One handed, too. A problem that I’ve been trying to solve for about six months has now been solved by a £3.49 application.

Combined with Apple’s own Remote application (which let’s you control iTunes from the iPhone, using an interface almost identical to the iPod control system) this is a step closer to my PC being a real media centre.

In short, if you have a computer connected to your TV, you dont just want it- you need this application. If you don’t have/want an iphone, then get an iPod touch.

It’s not perfect- multitouch drag and drop would be a great addition, and a hidden keyboard that would let you use the whole screen as a trackpad is a feature on it’s way that I like the look of. But it’s early days, and it’s already one of the few apps that I can see is going to really change the way I’ll use my phone and PC.
