Maybe I should jump on the Chrome wagon.
Don't forget to install the BBOS Chrome app :)
Getting in on this late, but my two cents on the issue. I prefer Chrome. Fast and easy to use. I never did get into using Firefox. Now with Firefox 4 out, we have issues with it working with the majority of web sites we use at work.
I actually also like IE9. Completely rebuilt the HTML engine. I like the design and it too is fast. Again, I have to use IE9 for various sites at work where Firefox or Chrome will not work.
At work, I strictly use IE9, but at home it is a combination of IE9 and Chrome. Using Chrome with anything Google web site is of course awesome. I use the Google Reader web site and Chrome works best with it as you imagine.
I'm a Chrome guy...but I do use Safari for certain things. I installed Firefox Aurora (Firefox 6 Beta) today, might try that for a bit.
