Give Your Phone the Power of a Desktop PC
Finding Mac OS X Portable Apps
Installing Mac OS X Portable Apps
Installing portable apps for OS X is a different process than for Windows, but still very simple.
The app will download in a single archive file called a "disc image." Once the image has downloaded, click it to open it. Open the Finder, navigate to your phone/drive, and then drag the portable app's folder from the disc image to your phone/drive. (Or, if you prefer, drag it to a folder on the phone/drive; I have a folder named 'OSX-Apps' to keep my Mac apps organized and separate from my Windows apps.) Once the portable app folder is on the drive, you can eject the disk image if you wish to get rid of it.
To run the portable app, open the Finder, navigate to the app folder, and click the app shortcut. It will drop into your Dock, and you can then run it as you would any other program.
Finding Linux Portable Apps
Linux enthusiasts who are smartphone users can get in on the portable-app action, as well.
Running a full-blown Linux OS like Ubuntu from your smartphone is probably the most powerful and customizable way to run portable desktop apps. You can access hundreds of software packages through the Synaptic package manager. Additionally, using portable apps allows you to create a system rescue option for disaster recovery.
On top of that, you can also run many Windows-based portable apps on Linux machines that have Wine (a Linux program that simulates a Windows environment) or Crossover (the for-pay, professionally supported version of Wine) installed. Your mileage may vary, but I have had success running PortableApps.com's Firefox Portable Edition in Wine on Ubuntu 10.04.
