Old: Brick = Power Adapter; New: Brick = All-Terrain
In the past, the "brick" has always referred to the BULKY power adapter. Back in the "old" days (circa Mac OS 9 or less), power adapters for even small Apple Printers (made by Canon) required a "Brick" that was nearly the same size as an Earthen brick and at least the same weight. That's how they got the name "Brick."
So, I'm sure that Apple is NOT working on making a new power adapter for MacBooks that is huge and heavy like a brick. Rather, its most likely a play on words -- as a parody -- for a forthcoming battery technology that will be lightweight and provide long battery life, etc. Basically, new and improved ... used to be a brick, now look where we are.
Or not!
Perhaps Apple's going INDUSTRIAL and will have a Rough, All-Terrain, Military like MacBook. One that's good for all environments: submarines, desert, arctic, space, secret "launch codes" you name it!
Perhaps an answer to Dell's has their
ATG line of laptops.
A REALLY COOL commercial for such a product would be along the same lines as Apple's iPhone "
Hallway" commercial that's totally NSA/CIA like in nature.
