I work for a web shop making websites for large brand name companies. I've convinced my boss to push our clients to drop IE8 support. My boss gave me a task to create a "deck" that can be given to clients. The deck will contain bullet points and information on why IE8 sucks and why their projects will be better leaving it behind.

So far I have:
* only 10% market share
* terrible support for advanced technologies like HTML5, CSS3
