Maybe the best reason to boot Windows
One of the technological highlights of TED was Microsoft's Photosynth. A way of mapping user-submitted photos to 3D models as a novel way of photo-mapping the world, it was absolutely stunning. The demo, linked above, runs in IE or Firefox, but only on Windows, but it's worth the trouble, both as an actual experience and as a hint of what's to come. The presenters had a great attitude regarding the common anti-MS sentiment of the world ("Who would ever have thought that there would be a Microsoft talk at a session called 'Simplicity'?"), and once they started showing their work, they clearly had no reason for concern. Take a look for yourself and be impressed.
