Apps take advantage of "cloud" services and let you access your documents wherever you are.
Sometimes it seems that the more mobile I am, the less mobile my documents become! Let me explain.
When I work at home, I occasionally use my desktop computers but write most of my documents on a Netbook. When I commute to work via the train, I use my iPad. Once I get to work, I spend the rest of the day on a desktop computer. Consequently, the documents I create reside on a number of devices, few of which play nicely with the others. I quickly realized that I needed an easy way to transfer files between these computers.
The solution for me was "the cloud." Google Docs, iDisk, and other cloud-based services let you store any file you’re working on to an online storage area.
