Fedora 9 32 or 64 Bit - Which One?

[Charlie McVeigh]

I apologize if this question has been asked before.   I have a new
Thinkpad T61 in scheduled to arrive sometime next week.  I want to
install Fedora 9 on it.   Being as it has a Core 2 Duo processor, I
assume I can install the 64 bit version of Fedora 9.  My question is
what are the pros and cons that I need to consider when choosing 32 or
64 bit version of Fedora 9?  I am currently using a Thinkpad T42
running Fedora Core 7, so I have no experience with 64 bit linux or
associated issues.

Thanks in advance for any and all advice.
