So, what if you needed a computer that was completely separate from your other computer? You can do a lot on your phone today. But what if you want a full screen and a real keyboard? Enter PortableApps.

I was working someplace where I needed/wanted applications I didn't want on my work computer. For that matter, installing applications (back when they were programs) was difficult as well. I found PortableApps and ran it and wiki on a stick from a USB drive. There were some real advantages. My notes, in the wiki were with me at whatever computer I was sitting at.
