PC users have log since benefited from great programs to remotely access the desktop of one PC from another.
With the convenience of carrying around tablets such as Androids and iPads, yet the inconvenience of not being able to run everything you need on these lightweight portable systems, accessing your PC remotely is still something many people have a requirement for.

$99/yr per PC, expensive, secure and reliable
Wyse Pocket Cloud Pro (Android and iPad)

My favorite is LogMeIn Ignition which I highly recommend you try out. They have Windows and iPhone versions as well. This mature product has become a required part of my toolkit.
