Alex Salkever feels that Apple’s hugely successful iMac line is due for a refit. In his latest column for BusinessWeek, Salkever notes that “Yes, the iMac remains profitable. By how much Apple won’t disclose, but certainly the line provides millions in net profits. And the iMac remains an important part of Apple’s income stream. It brought in about one-fifth of computer revenues in Apple’s fiscal first quarter and more than 10% of total quarterly revenue of $2 billion, which also includes the red-hot iPod as well as software and services. But in their earnings conference call, Apple execs’ silence on the issue of iMac stagnation was deafening.” [Discuss]
