Well, provided the other bits of the rumour stack up into a real product, that’s not particularly surprising. After all, could you imagine Apple putting Windows XP, Palm OS or Symbian onto its own smartphone? I don’t think so (mind you, how many people said Apple would never go to Intel…)
Now, that would be a tasty phone if you’re already a fan of what OS X provides. Truly mobile communication with iChat, appointments on iCal, a full Mail app. Of course, it wouldn’t get a full Leopard in there – the processing power and storage space wouldn’t be big enough – but it’s an appealing thought.
