It took me about 2 days before I stopped scrolling the wrong direction by accident every so often, now I am fully adapted to reverse scrolling and I think it makes the most sense. I have my BT keyboard and magic trackpad just sitting over my MBP's trackpad (Leaving about 2 inches at the bottom of the computer for my wrists) and because of the angle that they sit, it actually seems very natural to move the page rather than the scrollbar. My productivity surfing the internet (HA that's an oxymoron) has gone up dramatically, especially thanks to the inertia scrolling, it's so much more comfortable to surf the web the iOS way then the traditional way.
