There are only a few extensions missing from the Google Chrome/Chromium library that are limiting my complete conversion to Chrome on all OS platforms that I use.

I love Google Chrome (http://www.google.com/chrome/) - it's fast, sleek, lightweight, and now runs on all of the major OS platforms that I use. The only thing missing for me to make the complete switch (i.e. not having both Firefox AND Chrome open all the time) are a GMail checking client capable of accessing multiple GMail accounts, and a Twitter client with the same capability.
