I'm setting up a TruConnect 3G mobile internet on my laptop so that I can check email from anywhere. I have free wifi at school, and I went with TruConnect because it's cheap and I only need it for emergency backup when I'm not on campus.
Thing is, it's $5 a month and 4 cents per megabyte--which, at 3G speeds, can cost me up to $7 a minute in the minute it takes me to turn 3G on, check my email, and shut it down again. I already set up one of my browsers to not display pictures and other bandwidth hogs, but what I'm worried about is applications deciding to download updates.
I don't want to shut automatic updates down completely. I still want them to download while I'm on the school wifi. I just want to ban them from using 3G. If I have to click a button every day to "check for all updates to all applications," that's fine. I just don't want to update them one by one by one.
Is there an easy way to do that?
Or is it easier to just get Linux?
