How many times have you left important files or a program on another computer because you have forgotten to put it onto a floppy disk or burn it onto a CD? I know I have done this plenty of times.
One little gadget that I have found incredibly useful is a flash memory stick. It is a simple stick that can be hung on your keyring so you will not leave it at home, you just slip it into your PC and drag files and then you can take it with you where ever you go.
I am running the 2018 London Marathon to raise money for Livability UK in memory of my dad. If you can I'd appreciate any donation you can spare. http://uk.virginmoneygiving.com/deansaliba
