While reading a designer forum, I came across a conversation in which a self-admitted non-designer asked a question regarding why white space in design is important. She needed someone to point her into the direction of a web page, publication, or whatever that could easily explain this. One designer pointed her to this site, which I think is a pretty good example–in a humorous way. No disrespect to Microsoft, but there are more reasons to Apple's success in addition to just a great product. Here's the link. Enjoy!
