I have it - Google Chrome that is - and though have found it a little buggy whilst in beta it loads pages on sites like MySpace much faster than Firefox - like a previous poster I have not downloaded the latest Microsoft IE yet
It is too bad though, that most people don't follow Hitterman and uninstall IE. Go with something that doesn't try to set its own standards, and make my life/job easier.
Considered chrome for a day, it felt like I was using IE5.
Nothing can replace FF3 for now with all those great plugins ie. Firebug cant do without them.
I work for Microsoft - I love IE8B2... you just have to use the compatability feature to make sites look like IE7 again... i've never used the Chrome (and don't plan on it) and I've never been a fan of firefox...
