Have you heard of this term "Portable Apps" ?? When I heard of this term for the first time I thought it was some kind of application which is written in Java which can be easily ported to other platforms.. ;) But that's not the case.. The definition goes something like this
"portable - carried or moved with ease
app - a computer program like a web browser or word processor
A portable app is a computer program that you can carry around with you on a portable device and use on any Windows computer. When your USB flash drive, portable hard drive, iPod or other portable device is plugged in, you have access to your software and personal data just as you would on your own PC. And when you unplug, none of your personal data is left behind."
from the site PortableApps.
It's funny that oneside world is moving towards bigger machines with GBs of RAM for hosting faster/bigger applications and on the other side we have started looking for applications with small footprints that can be carried in a USB drive mainly to minimize the security theft of our data. I think employers should start forcing employees carrying sensitive data to start working with PortableApps thereby reducing the chance of data theft that has been happening recently with the reports of lost laptops with sensitive customer data.
I am surprised to see so many utilities/audio/video/games available for portable apps. I think one good outcome of this will be the shift in the developer mindset to develop applications with smaller footprint which has been lost in the past decade b'cos of the availability of huge storage spaces.
