Do you think in U.S. they are advanced than us in the Mobile Applications and Mobile Development?

No, I don't think so, internet now ease up the communication chanels required for learning and extending people's knowledge base.

Yes, they are but not becuase we are not great in development itself but it's about the whole cycle of work most of companies in egypt lack one of those (IT department, R&D, HR) or even all of them which makes the comaprison like a car race but one of the cars is missing one wheel.

From my point of view .. there is no nation or country smartest than any nation .. this is only depend on each preson what he do to be the best .... may in the U.s. peoples have more resources to learn but for sure now you can learn any thing at any where :)
