They could make the damned thing fuchsia-color with butterflies and dandylions painted on it and I'll buy it.
I think SJ/ Apple knows that.. they keep the mac fans in suspense, we buy anyway.
Folk that haven't ever seen a mac before that just happen upon the iMac or other mac in a store during a shopping trip THIS MONTH (please don't make me wait til August!) will likely say, "ooh pretty," and also buy! Win-win for them.
Apple is good at what they do..
