The problem with working at home is that the files you need are inevitably on your work computer. You can e-mail yourself the necessary files or carry a USB drive back and forth, but drop.io is a more elegant solution: a private file-sharing service where you can stuff your stuff. There's nothing to learn, just open drop.io, select the files you want to take with you, and when you arrive home — or anywhere with a Web connection — there they will be. It's a great way to share a lot of data with other people too: just upload your files and then e-mail or text people the URL "key." There are tons of other features for working with groups, but you don't have to learn about them to start using the service.
