New to this forum, I am looking for a "rule of thumb" policy which you might be aware of regarding upgrading from one Safari version to the next? Lets say, when Safari 4.0 becomes GA, what percentage of companies will move to 4.0 and what percentage will remain on 3.2 until 4.0 matures? What has the typical migration track record for new browser adoption been? I know that the answer might be "it depends" but just looking for managing product release cycles. Thanks for your help.
