Apple stock tops $500 for all-time record high

Apple's stock (AAPL) hit an all-time high this morning, passing $500 based on rumors of an iPad 3 announcement in early March and their recent $46 billion in revenue, 37 million iPhone sales quarter.

Apple stock sat at $457 at the beginning of February, jumping nearly $50 in less than half a month. This isn't usual for the technology market, but Apple has been an exception to the rule in this case.

Apple's current market cap sits at $466 billion -- the most valuable company in the world. The question is -- how high can it still go?
