I can't see how that would mean they ignore a whole sector of their customer base. That's like Mercedes going all out on a new A class and forgetting the E class altogether!
why do you think they are ignoring a whole sector?
New laptops will be unveiled at wwdc, because they want to show the new design in an event. And no, they likely were not in time for the march event.
The macpro is long overdue, i agree, but the update cycle for workstations is not as fast as that of consumer computers.
I suspect (pure speculation) that the macpro is more a display item for apple than a product for profit, eg. they would even sell it at a loss, but need the community of artists and professionals to stick with their machines, because that's the image they want to show off to people (think of how ipad pros are advertised, is that what common people do??).
the ad logic is: "cool people use my machines, they are famous and of success, so you'll want one too".
Also, you don't consider the revenues (and mostly the profits!) that the computer sector brings, which is small compared to those of iphones, so it makes sense to invest a smaller workforce.
Let's make another car example: the audi A2, it was a great car, it didn't sell enough, they never updated it, or should they just because few people liked it?
is whining over it ever going change things?
