Everybody has -by now- heard of USB drives. They may just be the true replacement for floppy disks, now that they are so well-supported in recent operating systems such as Windows 2000/XP, Linux and MacOS (just to name a few).
A couple of years ago I bought myself a 256Mb, USB2 Jumpdrive Pro from Lexar. It has been dangeling on my keychain for over a year, containing nothing but some pictures, and was used to copy files efficiently if a network was not present.
After reading some threads on websites, describing what people do with their 'pendrives', I decided to do some more research and carry a number of apps that will help me when I am at other peoples computers. For trouble-shooting, virus-scanning or just regular computer use.
What I love about most tools is that they are generally freeware and do not have to be installed. This means that I can run then from the pendrive and when I am done, there is nothing that needs to be uninstalled from the foreign computer.
The following list is what I have installed on my pendrive, first some special mentions, then the smaller files list:
Use: A complete freeware AMP environment (Apache/MySQL/PHP) for website development. Updates itself after being plugged in to another computer for the right drive name.
Use: Freeware FTP Client
Use: Freeware PHP Editor
Name: PHP Manual
Use: CHM-file of the PHP Reference Manual
Name: Portable Firefox
Use: Fortable Firefox browser, with portable bookmarks
