I first heard about this service on SparkFun’s blog.
Dropbox has a very simple concept: it allows you to seamlessly share files with many computers and users. It’s easier to use than a USB key. Installation is a breeze; the software works integrates with windows and the web interface (when you need it) is extremely easy to navigate! 🙂
You get 2GB worth of free space – which is very handy if you want to send files to friends or move them from one PC to another.
No more emailing files, spreadsheets, documents, photos, pcb designs etc to myself!
I installed it on my machines and recommended it to my friends – every machine should have this gem installed!
