Spettacolo... e non solo per i "contenuti"...

Although you may not have heard of them by name, Otto Group are a huge retail conglomerate with €9b of revenues in 2005/6; they own retail outlets like Crate and Barrel in the US as well as catalog companies like Grattan and Freemans in the UK and the eponymous OTTO in Germany.
As the second largest online retailer in the world, when OTTO decided they needed a fresh new retail experience, they wanted to set a benchmark for online shopping. The result was their next generation OTTO store application, built using WPF, WCF and CardSpace and available for download today from their website using ClickOnce technologies. I'm so impressed with what they've built: it's a really attractive experience that will undoubtedly result in increased sales and improved customer satisfaction.
