Take your favorite apps on the go! Here's a reason to get a portable USB flash drive if you don't already have one. PortableApps, provides slimmed down versions of your favorite desktop apps that can run solely on your USB flash drive. The list of apps that are offered right now include Firefox, Gaim, and Open Office, just to name a few. Check here for the full list. If your company does not allow you to install chat programs or Firefox, this is definitely for you.
Download the Suite if you want all of the recommended apps and space is not a concern on your flash drive. I personally got the Lite version (still 30mb) and got Firefox, Gaim, and ClaimWin (antivirus) installed on my 128mb I got laying around. The total disk footprint is about 45mb, which is fine for me since I mainly use my flash drive to move single documents/powerpoints around.
