Some interesting reading about rackspace vs AWS in terms of price/performance
reading the hacker news thread I can see that beginning of a new religion - which cloud provider do you use? its going to be one of those windows/linux, firefox/IE wars... and ultimately there no real way to say which one is best, as it depends on what you need.
I moved my hosting from a dedicated server (windows) to a AWS micro instance (linux fedora). Its only been running for two weeks, but its only cost $10 compared to $50 - of course I had a physically dedicated machine before, but the micro instance seems happy enough running email (postfix). I'll write a post about setting it up later. So the cloud will save me $1000/year - not bad!
