I just read this article about Portable Chrome via USB on JKonTheRun about using a portable version of Chrome for the Netbook type:

jkOnTheRun article:

They got it from here:

And that article also mentions how to create multiple “profiles” in Chrome. I won't be doing this as I don't really have a need for it at the moment and am too lazy to go through the steps for mere amusement. I think they'll add this in as default eventually, but for those who are interested:

What's use to that? It's not like Chrome is 1Gb big application so they need to make a USB version, it's light and can be installed on just about any Windows system.

buddy….but portable….app..is also good…cause ther is no need to install  just copy and paste…
