Recently well at best a week ago I come across an awesome App for the iPhone the Air Mouse.
Air Mouse is not like any other iPhone App that lets you control the PC from the Lounge (If you have a Home Theater PC setup) so no having to get up all the time to get things going.
I use it on my Home PC and Work Mac’s and it has been working flawlessly from the get go little to no lag at all as it uses Wireless but has had maybe 2 little hiccups but that is to be expected.
The app can be bought on iTunes for $2.49 Australian or something like $1.99 American or something like that I don’t know how much American but I feel ripped off lol
Also you will need to download the Air Mouse Server software for either Windows or MAC
Anyway here are some Snapshots of the App.
