Comparision would be great....
Some situations showing different costs would be good - although that could be quite complex depending on needs - ranging from small business, to large enterprise business - to people like me - someone hosting a handful of websites for friends and family,etc. (and like to have a server to "play" with) who's bandwidth and resource needs are next to nothing.
It did take me a long time to work out which solution was best for me (price vs all the options) - if some form of "here is a platform, we only charge per month for what you use" was out there, that'd be great (as mentioned, I hardly put a strain on resources (simple LAMP stack) and a couple of gig's of disk space).
