There's a good article on CHROME on today's wire. I thought it was a fair evaluation.
Overall, CHROME seems to use less of my processor than IE or FireFox. Whereas IE feels like a heavy hog, CHROME feels light, with FireFox somewhere in the middle.
I like it, but it all comes down to what you want in a browser.
Last thought: If you're looking for bells and whistles, you won't find them on CHROME. This product was build for funtionality. It is designed to get you where you're going and get out of the way. I doubt that will change as they move beyond BETA.
So, if that's what you want in a browser, then you want CHROME.
