LogMeIn Ignition for Android $14.99 (50% off)
'Access your computer from your Android, and never leave anything behind.
50% off for a limited time.' An extended Cyber Monday sale I think.
I use LogMeIn Free to support clients computers from my home. This Android software does the same thing from an Android device. There are quite a few brands of this kind of software - LogMeIn is one of the better ones.
