I'm on a Mac and even I don't use Safari...
I'm not sure Apple honestly expect it to take much of a market share, at least in the short term. They understand that those who care enough about their machine to download a decent browser are already going for Firefox or Opera. It will be very hard to break that unless they have something more up their sleeves.
I'm curious as to why you would select IE over Firefox though if UI is an issue, as IE7 has by far the chunkiest and most unpleasant interface of all the browsers (except maybe Safari on the PC ) The Firefox plugins/add-ons on their own were enough to get me to switch in my PC days.
