I tried Google Chrome back in September when it first came out.
I trade stocks on Scottrade. Their stock trading platform uses your internet browser to some extent. Once I downloaded Chrome and identified it as my default browser, my stock trading screen would periodically turn to molassas, that is to say it became very slow. I tryed to close all my stock positions a day or two after installing crome and I couldn't get the trading screen to accept and send the order. As you can imagine, my blood pressure must have gone through the roof. My sell orders didn't go through. That evening I uninstalled Chrome. The next morning I was able to sell those positions without any issue for more than what I would have gotten the previous afternoon.
Although this turned out to be a happy story, had the market gone the other way and it had cost me a large bundle, I'd be looking for blood.
I think that eventually they would get that problem resolved, but I'm not likely to give it a second chance on the computer that I buy and sell stocks with. On another computer, I might give it another shot.
