In the age of cloud computing, there’s no reason work should stop because the file you need is sitting on some PC out of reach. Every time you switch computers and email a document to yourself, you’ve wasted time.
Use online storage and syncing services to keep everything you need at your fingertips. Dropbox, Microsoft SkyDrive, and Google Drive each keep all of your documents in the cloud, accessible from any PC or device with a Web browser. Evernote and Microsoft OneNote run on nearly any platform, and are ideal for keeping track of information you've captured on the go.
