Dropbox
You’re all web savvy people so you’re already using Dropbox, right? If not, you’ve got to check it out. It’s an amazing tool and website that lets you store and sync files across any computer (at home, at work, Mac, PC, linux, etc.). I use it so a bunch of friends can work together on a project and to keep files in sync between home and work. If you’ve ever found yourself emailing yourself a file, use Dropbox instead.
(Also, if you use the link to Dropbox from this post, I’ll get a free extra 250Mb of storage so give it a shot. It’s free!)
