I can't respond to the first part without sounding very condescending indeed. The second part, however, I can confirm is nothing more than a myth. A couple of reasons: Google Chrome is Google's distribution of the open source Chromium browser, meaning that any such privacy invasion would be discovered in the code and widely reported. Google has made it very clear in Chrome's EULA that no information outside of Google's own pages, say Gmail, is sent to Google and they claim no right to it. It would be nice to see your sources. I'm not disputing your first claim very much- I remember seeing speed tests in which IE9 beat Firefox by a small margin- but your second claim doesn't seem to have much ground to stand on. However, there's something I would like to note. Even if IE9 starts to outperform Firefox/Chrome/Opera/Safari, there's a good reason. IE9 was one of the first browsers to introduce GPU-accelerated web browsing. What this means is that the existing Trident engine isn't actually optimized, it's just being run on really fast hardware. So when Chrome, Firefox, etc. get around to finishing their GPU acceleration, their cleanly implemented, modern engines will blow IE off the face of the Earth.
