EDIT: On my website Vista use has been slowly climbing. Out of ~17000 hits so far this month 18.4% are using Vista. For browsers: 43.7 % are using IE (30.8% for IE7, and 12.8% for IE6), 47.2 % for Firefox, almost all using the latest version.
I'd strongly suggest making your launch site Firefox friendly. As you can see, vista use is still fairly low (though climbing as people upgrade their computers obviously), but Firefox usage has been surging hugely in the past 6 months. Only a few months ago FF2 usage was in the 20% range.
