Running Portable Apps on Linux
Many people have heard of Portable Apps and are probably wondering if they will run on Linux. Portable Apps (as distributed by PortableApps.com) are not made to run on Linux, but I have been able to get them to work on Linux under WINE.
Here is a screenshot of a couple of the Windows versions of Portable Apps running on Ubuntu Linux from a USB thumb drive:
I was able to get all of the Portable Apps Suite to run on Ubuntu Linux with WINE, except for Portable Gaim and Portable AbiWord. The only real function I can see for this is to be able to run your regular copy of Portable Firefox, with all of its saved settings, on a Linux computer.
Linux has all of these programs already, so if you are just looking to use functional programs, a live CD like the Ubuntu live CD will have equivalents to all of those programs. With a live CD and a USB thumb drive you can have access to thousands of programs and you will be able to save all of your settings back to the USB thumb drive. Certain Linux distros like PCLinuxOS, Slax, Knoppix, and Puppy Linux have built-in features to save your settings to a USB thumb drive.
