Apple "Today Apple announced the MacBook Pro. It has quite a few changes compared to the previous PowerBook. For one, it uses an Intel Core Duo (formally known as Yonah) chip. This is a dual core processor and no, unlike what Steve Jobs stated, this does not have two processors. This will help a lot with responsiveness. I've been dreaming of a dual core laptop for quite a while. However, the realization of my dream coupled with the changes seen makes me cry", writes Unsanity. UPDATE: Windows XP won't run on the new Intel Macs because of EFI. Vista is supposed to work though.

Wait, the new Macs are 32 bit? Good grief, Apple spent all that time and money getting 64-bit systems and now they've gone to dual-core 32-bit processors? That either means 64-bit isn't so great, or Apple was desperate

Actually they didn't do much work at all on 64-bit. The only 64-bit machines they sold were the iMacs, PowerMacs and XServes: the iBook, PowerBook and MacMini were all 32-bit. Further, most of the OS, particularly in user-space, was 32-bit as well, with the exception of memory addressing and a fast math library.

There's a very good reason for this. Fundamentally, the home user doesn't need 64-bit, which only pays off for high-end maths or apps that need gigabytes of memory like cinema-quality video editing and enterprise level databases.

The only machine you'd use for that kind of stuff is a PowerMac or an XServe, and it's fully expected that by the end of the year (the given time frame) the 64-bit Intel "Conroe" chip will become available and will be used to build these computers.

Or the correct answer, which is: the majority of OS X wasn't 64-bit clean anyway. 64-bit apps on a 32-bit kernel might work on PowerPC, but doesn't work on amd64. To run 32-bit apps and 64-bit apps concurrently, you need a 64-bit kernel.

Aah, so it was just hoopla and marketing.
