Its also good because from the U3 website, you can download a lot of apps that portable apps has to offer (such as anri-spyware and AVAS! anti-virus-but they do have clamwin). U3 is ok because it has password protection (as mentioned earlier) and it loads on insertion on all computers with functional USB ports (it doesn't use an autorun file which only works on most XP and newer OS). You can't update firefox to 3.0 or to 3.0 for U3. Firefox, thunderbird, and sunbird by mozilla, along with for U3 are made by PA.com.
