That's how it works for markets but not individual products.

Cellular phones started with professionals, then prosumer, then consumer. The iPhone followed that track only because the market was significant in all areas, but it's worth noting they don't really have a "pro" phone.

Likewise, a lot of their pro gear is really expensive to engineer and the sales are thin. They'd rather make prosumer and consumer gear that they can crank out in volume.

Can't blame them, really. The entire PC market is imploding, so it's a lost cause to try and carve out new market share when everything's going to hell.
