What is the difference between a leopard and a lion? A leopard is high frequency, illusive, strong, fast. A lion is strong by his weight and the support of the pride, a bit arrogant, because he knows he is strong and got the pride to back him up and because of that intimidating towards others.
Apple made the move to "Lion" and the reviews are essentially the same. Its slow, not as fast as "Snow Leopard", not as flexibel, not as easy to do more things at the same time.
It might be the visualization of the changes within Apple. The leopard has gone, the lion are left. Apple a pride of lion?
