Working for Microsoft has many benefits - an obvious one being I don't have to pay for Visual Studio, which means I simply install the top of the range SKU. Hence I am running Visual Studio Team System 2008 Team Suite (catchy isn't it :)).
But... the early adopters I work with often are not using the full product once we exit beta and ship. At which point it becomes important to understand which features belong with which SKU. Hence I was very pleased to find the official (and very detailed) Visual Studio 2008 comparison page. Just what I needed.
