My laptop is set up to download new podcasts every 6 hours. Normally, this is a good thing, particularly when it is at home. However, my work involves night shifts. There is no usable network available so I have to tether to my phone. Now, my data allowance is variable, depending on how cheap I am feeling when the previous allowance runs out. Having my computer chew through that downloading podcasts is not desirable.
Having just done a run of nights, my laptop never attempted to grab podcasts in the time I was at work so I consider this a success. No more panicked unplugging of the USB cable and killing the service, only to do that again 6 hours later.
