One great trend that we’ve been seeing lately from software vendors is the availability of a portable version of their software for Windows environments.
Installers serve an important purpose for more complicated software packages. However, in many cases they aren’t necessary. Many applications can run standalone using a main executable and a small set of supporting files that ship alongside it.
In that case the installer brings overhead that is unnecessary. Providing a portable version makes moving the application or using it from a thumb-drive really simple. One of the things I love about my iPad is that I know when I delete an app that it is gone completely, not using up space or leaving cruft behind. Portable versions of applications are a step towards that in the Windows realm. Good to see.
