Sorry about that. Basically what happens is, when you talk to a Web site, you don't talk to it directly. Your communication TO that Web site is intercepted by a Google proxy server. It then passes your communication on to the Web site, and when the Web site responds (like sending you the Web page you want to view) it sends that data to Google, who then compresses the data and then sends it on to you. If the Web page you want to view is 4 MBs in size, Google can compress it down to (theoretically) 2 MB. So what you get is 2 MB of data rather than 4 MB of data, thereby saving you bandwidth. Some Web sites won't be compressed that much, others will be compressed more than that.
It's really all about what you like, what your preferences are. All browsers have their pros and cons, their little features. Out of all of them, I still prefer Dolphin, mainly because it works seamlessly with LastPass.
