I've mentioned Apple's Safari browser on the show, and it seems to work fine except that there is a nasty security flaw in it that basically allows executable files to be downloaded invisibly, and combined with the Windows automatically opening files, this can create some real danger to your computer.
At this point, I am not sure who will provide the fix - Microsoft says they "might"; presumably, Apple is working hard on it.
I recommend not using Safari until either Microsoft or Apple addresses the problem.
