"Hi Dave, Just a quick thanks for this page; I worked through it back when you first posted it. In fact, I'm doing a small presentation on cloud computing and I will be using this page as a starter. I think it will be very useful in showing up some of the B/S that has grown around the topic. Having said that, one minor fix that may be worth adding - I don't know which region is the default for 'first timers', so it may be worthwhile adding a line about making sure that the region is set to US East (virginia) when looking for the ec2ForPoets images Once again, thanks for curating this" - martin english
