If you can get a MBA with a 256G SSD for $1,599, why is an SSD upgrade for a MBP $750? It seems like Apple is taking advantage of the consumers who can and will pay for the upgrades available in the MBP line. By offering this very desirable drive in an affordable MBA, they're kind of admitting to us all that they don't have to charge that much for them ... I think they should lower the price of the upgrade for the already very expensive MBPs... Am I crazy?
