In a long-winded bit about components and the future during Apple's earnings call, Apple COO (and acting head honcho) Tim Cook talked about how, in 2005, they invested a lot in securing agreements and pre-payments for tons of flash memory - around $US1 billion worth - because they thought it'd be important in the future.
Well, he says, Apple's identified another area where they've started investing like they did with flash - agreements and pre-payments - where they feel they can innovate, but they're not ready to talk about what that area is. Iiiiiiinnnnterrrrresting.
Maybe crazy high-res displays? Hmm.
