The first iMac was revoloutionary in the idea behind it, the second iMac was a bit of a revoloutionary design but nothing special in the idea behind it. I think its time apple did something more revoloutionary again and less evoloutionary, even if it means bringing in a whole new line of computers to replace the iMac. I think they should be more focused on a digital hub idea, and with the ipod, airtunes, airport etc a lot of the groundwork has already been laid.
