I have a laptop which I've decided I want to use for certain things (coding mostly) and leaving the 'fun' things for my mac Mini. I want to maximise disk space on my MBP. As such, I have deleted iTunes and the iLife applications. As I access all my PIM stuff through the web, I had considered deleting iCal and Mail also, as I will never use them. I know that I can install iLife again if I need it. I'm not so sure about Mail and iCal. Is it safe to delete these? Could I get them back without a full OS reinstall?
