I was on MSDN live a couple of days ago and on one of the stands they had this competition: Write the coolest azure app within a couple of months and win a Windows 7 Ultimate. Great, I would like to try out some azure programming, but it got me thinking, how would a azure app stand out from normal web apps. Basically it is just the hardware that's different, but it forces you to write your app somewhat different.
What are some examples of cool apps that clearly is easier and better suited as a cloud app than on a normal web app?
