If it walks like a snake, talks like a snake ....
No disrespect, but I'm not the least bit impressed.
In terms of Google Chrome speed, on this computer, it is not dissimilar to Opera's latest, among others.
Right now, out of the popular Web Browsers, Opera and Seamonkey are one of the few web browsers I trust. Okay, Seamonkey, not as popular, but I find it much more stable than Firefox.
To me, mainstream means trouble. I prefer browsers more away from mainstream such as Konqueror, Midori, Netsurf, and Dillo. You might find them faster, too. More of an essence, you should find them much more safer, because feeble-minded virus programmers invest on a big catch, predominately - the mainstream web browsers. Plus these Open Source browsers intentions are more clear than Google's.
In terms of security, I find some of Google's practices questionable. By the way, I notice on a MS Windows machines Google Chrome chooses to install on administrators account, strictly. Which is unsafe, the least, let alone, suspect.
Also, the Youtube Downloader is another suspect program (as identified by Eset Smart Security for Windows). You would figure Youtube would provide that feature by default. As to: why not?, It would appear as another questionable practice.
No disrespect, I could be wrong about people running machines as testers, but in my neighborhood people put out testers curbside from time to time. I had grabbed one myself, only to test software with it, but ultimately, don't make it your main computer. Invest, you deserve much better than that.
Above all, don't frustrate yourself or waste time.
Futhermore, I would question any company that releases a watered down versions of their product (like Picasa) for Unix and Linux. I don't see Unix and Linux as an afterthought, neither should they.
