I would say the big tip of was when Apple Computer became Apple Inc. They are focusing more on gadgets then computers.
I think part of that has to do with the fact that gadgets are now more a part of the computer world than ever before.
When Apple first (like most other companies) got into the computer business, the computer was a stand-alone device for the most part. Sure, a printer (if you could afford one), maybe a few other niche things, but that was it. Now, your computer is your TV, your phone's hub, your method of written communication (who still sends out regular mail?), your music organizer, etc. Apple is offering you a computer and everything else (literally) you could/would need/want to go with that computer. It is not only a survival tactic, but it seems to be a flourishing tactic as well (from a business perspective).
I think that as long as Apple stays on top of its computer line (ie, doesn't neglect it), more gadgets are only a good thing. It gives me more choices, and pushes for more innovation, because let's face it: no one innovates like Apple.
