The BBC's iPlayer is a reason all by itself to buy the iPad. It handles streaming content via a Wi-Fi connection seamlessly and, as with the full-fat website, gives you catch-up for much of the corporation's output. The catch is, of course, that it's UK-only get to it via the BBC website and then put a link to it on your desktop.
Very cool recommendation. We love reading our news and watching companion videos to the news on the app. BBC's content will be a great addition.
