Have heard directly from a very reliable source that the 17" LED backlit MBPs will be arriving in stores very soon. Very soon as in within 2-3 weeks... I'm personally waiting for this greener feature, plus Leopard and then am ready to step up to the Apple Store cashier. (Blu-ray would be an added bonus, of course, but feels like that probably will not be out by October.) Anyway, assuming this particular rumor is true, would indicate that LEDs are soon coming to Macs in sizes other than 15", which would bode well for the new iMacs and, I'm hoping, for Cinema Displays.
