When traveling it is sometimes easier not to bring my laptop along because I will have access to computers at my destination. However it can be a hassle not having important files that I might need and my browser with my personal log-ins and bookmarks that I have become so dependent upon.
In this circumstance I like to use a flash-drive with an application suite called Portable Applications installed on it. It is a combination of a number of the most popular open source programs and easily runs on any Windows XP or Vista computer.
Now you can carry your favorite computer programs along with all of your bookmarks, settings, email and more with you, and use them on any Windows computer. All without leaving any personal data behind.
PortableApps.com provides a truly open platform that works with any hardware you like (USB flash drive, iPod, portable hard drive, etc). Its open source is built around an open format that any hardware vendor or software developer can use.
The PortableApps.com Suite and Platform is free. It contains no spyware. There are no advertisements. It isn't a limited or trial version. There is no additional hardware or software to buy. You don't even have to give out your email address. It's 100% free to use, free to copy, and free to share.
Portable Apps has the choice of either getting as a suite or you can pick specific applications that can be loaded on your flash drive. The Port Apps' suite includes Open Office product, Mozzille's Fire Foz Browser, Thunderbird email client, and about a half dozen other popular free open source programs.
