Here's another review of this new Intel Core Duo based notebook from Apple, this time it's from ARS Technica. Here's a snip:
Well, there was one exception. A mere day before they were originally slated to start shipping to the masses, Apple bumped the chip speed of both the high- and low-end models of the MacBook Pro from 1.83GHz to 2.0GHz and from 1.67GHz to 1.83GHz, respectively (with a 2.16GHz version available for built-to-order machines). While mystifying, no one was arguing with that, even if it did push everyone's shipping back by one more week.
