I think it is a good idea for PC users to backup their files after they downloaded the file, or created/saved it with a program like MS Word. Computer viruses can delete your files if your computer gets infected, and hard drives and other storage devices can randomly break, or get stolen if someone steals your laptop.Hmm... Looks like I should consider backing up my files as well. My laptop isn't going to last long now.
Ugh I really hate the life time a laptop. It's too short.
How I wish I could extend it but no one can do that and it all depends on luck I suppose.
