Are the latest Macbook Pro's 64 bit?

Simple question, maybe not such a simple answer as I admit to not knowing really what 64 bit means in practice. (Although I know what it is in theory).

Anything that is Core2Duo is 64bit, althought the current difference between 64 and 32bit will be virtually nonexistant in everyday task for a little while ...

EDIT: Currently the real difference is that 64bit allows for more than 4GB of physical RAM - although currently only the Mac Pro can actually handle that.

I see thanks. So does that mean that by buying a current 64-bit Macbook Pro one can take advantage of any upcoming 64-bit applications/benefits that are likely down the line? How long before it's going to make a difference?

Yes, getting a 64bit MBP will benefit you down the line, however, I dont know how long before developers start taking real advantage of the benefits.

Leopard is 64bit.

Getting one that is sets you for the future.
