PortableApps.com Suite – Your Digital Life, Anywhere

One of the difficulties of traveling, especially if you don't have your laptop with you, is leaving behind your bookmarks and email settings.

Fortunately, there is now a portable alternative that fits into even the tiniest USB flash drive. PortableApps.com provides a completely free, portable, and open source solution for the person on the go: The PortableApps.com Suite.
