If I could only pack three tools in my eToolbox… [this is like the game "If you were stranded on a deserted island and could only bring three things," except there is no island. Bear with me.]… I would choose Twitter, Evernote and Dropbox.
I have used this tool for the past 3 months, it's nothing less than excellent. No need for zips drives or problems like: "darn, I have that file on another computer". You can get to all of your files on any computer that you load Dropbox onto. I believe that you can sync up to 5 computers under one FREE account.
