Interesting to compare both philosophies, each valid in it's context based on experience of the designer. The moral is: "There isn't always just one way", and the daydreaming newbie can always come up with something new. That is meant to encourage newbies, and not to characterise either party in the current exchange. TNX for the opportunity to watch prolific minds volley!
