Everyone has experienced the need to access their computer - home or office - when out and about. Whether you have forgotten to take a copy of a file you need to work on, or simply want to shut down your machine without having to hop in the car to do so, the uses for remote access are almost endless.
Using LogMeIn Ignition, you can use your Mac or PC from your iPhone or iPad as if you were sat in front of it. There are obviously compromises to be made due to the smaller screen sizes, particularly in the case of the iPhone, but the app has been designed in such a way to negate this problem.
Getting up and running could hardly be simpler, and you should be remotely connected to your computer in a matter of minutes. Your remote sessions are password protected and encrypted to prevent snooping, and you can configure profiles for multiple machines if you regularly remotely access several computers.
There is no getting away from the fact that iPad users get a far better deal here, but the retina display of the iPhone 4 does an excellent job of displaying the contents of a full sized desktop. On the negative side, while it is possible to remotely shutdown a computer you are connected to, a lack of support for Wake On LAN means that it is not possible to switch them on.
LogMeIn Ignition is likely to be one of the most expensive iOS apps you will buy, but it will pay for itself in next to no time.
Note that this is the major v2.0 release which includes a File Manager for copying or moving files from your mobile device to/from your desktop computer.
