Like Wes, I also use the Google toolbar. It's awesome. Get it if you haven't yet. I just wish I could install it at work!
And for those who aren't wise to the Way of the Google - check out the Google Labs or the other Google Services & Tools.
I'm the biggest advocate of Google. My homepage is Google News, I use the Google Web Search exclusively, and Froogle as much as Pricewatch now. I've also found Google Catalogs great, especially when I was shopping for furniture - besides the fact that the technology itself is pretty damned cool.
