Thumb or Pen Flash Drives

We were laughing the other day about how many peeps we know own and carry with them a thump or pen flash drive. The average capacity is 256 megs and they are so compact and come in handy in case of an emergency. So what do I carry on mine? Well, my 128 meg holds the following applications: Spybot Search & Destroy, AdAware, AVG Anti-virus, Smart Photo Recovery, Belarc Advisor, Sygate software firewall, Firefox, Irfanview and Strip Mail.

The idea is that if I stumble upon someone who has a virus, spyware or photo recovery problem (and I have), I can assist them in a heartbeat. Irfanview and Strip Mail are two small but handy utilities for photos and cleaning up email before forwarding, respectively. I may look geeky for having a thumb drive, but that's okay. I like being prepared! LOL What are your main utilities that save you time and again?
