I agree that business should be a focus for Apple. Back in the Lisa/early Mac days, Apple was very intent on the business market. As Wintel became prominent over the years, the Mac got the reputation of being good for graphics...but little else.
People tell me this all the time. And I tell them that yes, the Mac is better at graphics, but its better at just about everything else too.
Perceptions in the IT&business markets will weigh heavily on Apples future market share. Consumer attitudes are changing, now its time for the corporate.
