I’m not intending on listing any portable applications to go on your usb drives, ipods, or memory sticks. But I’m going to list the places that have them, or I know will list them in the future.

PortableApps - This is the big daddy of portable application sites in my opinion, while it doesn’t have as many apps. It has the more used and practical ones like Firefox, Thunderbird and Open Office. Along with their own software packages.

Portable Freeware - While the site layout isn’t that great, there are a lot of apps on here that can be useful.

PenDriveApps - I’ve only come across this one in the last few months, not lots on there but the useful ones are.

LifeHacker - Lifehackers list of portable applications with short reviews.

GetUSB - I just found this in Google, looks interesting!

Xtort - Freeware files, including portable apps.

U3 - U3 are USB drive with their own preinstalled package. While the freeware portable apps do the job you may like something a little more standardised. But U3 does offer some free apps in their database so have a look what’s on offer.

Wikipedia - No applications on here, but a big list of the portable applications avilable to install on your USB drive.
