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.

32-bit?

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.
