I've been using Dropbox a lot recently to share files with friends and colleagues. It's a simple multi-platform app which integrates neatly with your OS and looks just like a normal folder, except the files are stored online. Every device you connect can see these files. It's like the thumbdrive you never forget.
It works with Windows, Mac, iOS devices, and, I assume, Android.
My ulterior motive for posting is, of course, referrals. If anyone fancies trying it out, please use my link, so I can get extra free space in my 'box.
