Google Chrome. No need for anything else. It's fast, it's lean, it just works (except for Windows 7 beta downloading but I can live with that). Perf ftw. IE is no serious loss, seriously... Let's see how the final turns out; bets are on that it is aligned
with the Windows 7 timeline. But so far, no negative thoughts sent towards Brussels from this point. I like the tagline that Windows 7 is the Chrome of Windows.
