Dried Up Apples?
So is it graphic designers themselves who have been deserting Apple in recent years, leaving Apple to believe that there is simply no market for them anymore? Unlikely, as the news that the Mac Pro line may be in danger has not been met with industry approval. Even if the market is slowing (and aren't most markets slowing right now), there is still an industry there that needs to be supported, even if it's on a smaller scale.
It's possible that Apple has lost a grip on the pricing, leading to slow sales. Although the iPhone is the most popular smartphone around, everyone would agree that it's prohibitively expensive, and is a reason why Apple is continuing to sell older models like the 3GS and iPhone 4, so they can attract part of the mid-range market.
Everyone is having to tighten their belts right now, so it's entirely possible there's just less cash for businesses to invest. As impressive as Apple products are across the board, they are definitely overpriced -- in fact the top 12-core Mac Pro retails for $4,999 which is no bargain in anyone's book. So perhaps getting rid of top end Apples simply means they are a victim of their own making. Perhaps. Or maybe they have something else up their sleeve.
