On my screen, approximately 2/3 of the width is white. Why all the wasted space? I don't do my development on a mobile device, and don't read this website on one either. What's wrong with letting the content size according to the space available?

Adjust the width to the available screensize. With a fixed size you will never please everybody.
An automatic sized width can easily be read on computer screen (independent of mail readview pane), laptop, readers and mobile phones.
