64bit awesome!!
Best thing about Leopard.
Now that will make 3rd party application developers make 64bit Apps.
Photoshop 64, bring it on.
I am a bit dissapoited that Final Cut Studio 2 is not full 64bit

It has been said that there'll be no 64bit photoshop for quite some time because it would lock out a lot of its market, upsetting really! I would love to build a budget PC with 8GB of RAM then paint of very high resolutions
Yer all the main Apps. that are 64Bits are 3D Apps like 3D Studio Max, Maya, Soft Image and so on. Mostly on Windows.
It wont be at least 3 years until 64bit Apps become mainstream. I mean we struggle to get apps that take advantage of dual core.

I have a feeling that a lot of applications from Apple (once Leopard is released) will be something of a "Universal Binary" in form...that is, one download, and it can tell if it needs to run 32-bit code or 64-bit code. At least, that's what I would do, to take the guesswork out of it for the consumer. Although, with as many chips are out there now, this would almost effectively quadruple the required size for the binary (PPC 32-bit, PPC 64-bit, Intel 32-bit, Intel 64-bit code ALL required).
Thank GOD for apps like XSlimmer!

Any Intel based Mac that has 'Core 2 Duo' (notice the 2 in the middle) is a 64 bit processor-equipped computer. The iterations with just 'Core Duo' are still 32 bit.
In short answer, a regular MacBook with a 2.16 Ghz CPU is indeed a 64-bit machine.

The G5 is an interesting chip as you can run it in 32-bit or 64-bit operating systems. But even in 32-bit operating systems, you can do 64-bit integer arithmetic.
With Windows XP (Vista is the same), there are two versions (essentially) 32-bit (Media Center, XP Pro, XP Home) and Windows XP Pro x64 Edition. The latter is a 64-bit operating system that can run 64-bit native apps or 32-bit Win32 apps.
One of the benefits is that you can use far more memory on a 64-bit OS and application but it comes at a cost. 64-bit programs can use up to twice as much memory as 32-bit programs as pointers are twice as big, instructions are larger
to deal with larger addresses and larger integers.
So loading time for programs can go up and you really need to have more memory for a 64-bit system than you do for a 32-bit system.
The x86-64 architecture gets a big benefit from
16 general purpose registers instead of 8 for x86 and 16 vector register instead of 8 for x86. x86 is generally constrained for registers and having more means that program modules with a lot of variables can see better performance.
I'm the only person in the world doing Windows 64 Firefox builds and you can see the performance improvement from 32-bits to 64-bits. I would like to do something similar on the Mac but I need to get a Mac (other than my PowerMac G5) first.
The obvious one is we can finally use that 4 Pebibytes of RAM we have in the cupboard (Theoretical Maximum)
Or is my math/computer science wrong?
Well, in reality we need to move away from the current 64GB limit of 32Bit (or am I wrong again?), seeing as the X-Serves now ship with up to 32GB, it won't be long before 64GB is available.
(Theoretical Maximum)
