Does upgrading cost?

True, there are no upgrade prices on these products that I have seen. If you just bought your Mac, it might be worth taking it back for a refund and re-purchasing after the event.

Or, I have heard stories of kind Apple store staff upgrading certain things like OS X or iLife software anyway even though they were under no obligation to do so, but I wouldn't bank on it.

If you pursue the refund and repurchase strategy, you still may not get the latest stuff instantly after MacWorld next week - that depends on the actual shipping date of each product - but you may qualify to get it as soon as it's available for no extra cost.

 

not to mention he probably opened it, so the restocking fee is MUCH more than just buy those later
