I was cleaning up my mac before handing it to systems on my last job. I had a couple of days just for the Knowledge Transfer of projects and nothing else. I have always run two or three passive self policing apps like Rescuetime and Timing etc.,

It is good to know your usage, the 10GB fair usage plan from Airtel is peanut for my usage as I download a lot of TED & iOS Dev videos from iTunes.
