Apple isn't successful because of Macbooks, Mac minis or iMacs.
Bulk of Apple's success is from their iDevices and its surrounding ecosystem. iPod, iPod touch, iPhone and iTunes app/music sharing infrastructure.
So in many ways Apple isn't a computer company anymore. Its more like Sony nowadays. What you will see in the future might be computers dying a slow death in the Apple ecosystem. Expect things like TV, Stereo and other entertainment stuff like Gaming consoles gaining more traction.
Slowly but steadily Apple is transforming itself into a consumer electronics company like Samsung.
Actually, Samsung sells pretty much everything a company could possibly sell, even weapons. I know you mean Samsung Consumer Electronics, but it's a tricky example because the network effects (or lack thereof) between all of Samsung's subsidiaries are not obvious.
Also unlike Samsung, Apple depends on OS X as their developer OS. The whole WWDC was praising developers for helping iOS take off, and I think rightly so.
That is certainly where their money is, however they built a lot of their existing consumer business on the goodwill from people who were loyal Apple computer users. All of the original iPod users that I knew where loyal Mac computer users (partly because the software didn't run on anything else at the time).
I wonder what would happen if they decided to abandon their Laptop/Desktop business and go purely for consumer electronics? This would certainly piss off many of their loyal fans such as graphic designers/musicians who aren't exactly going to be looking to go back to Windows based PCs for their work and could damage their brand.
Perhaps they will launch some sort of "Post PC" device intended for serious work, for that I am thinking something along the lines of the chromebox.
