So this graph is not scientific at all but I did my best to estimate. I found that my MacBook Pro usage dropped from 60% to 20% post iPad arrival. My iPhone dropped from 30% to a measly 10%. Let's not even talk about the iMac... I think I saw it shed a tear the other day... Anyway the full graph can be observed in the link. http://theurbangeek.com/2010/04/12/how-the-ipad-changed-my-life/ I'm really interested in your experience and how your device usage has changed or altered thus far. Thanks.
