Office 2010 64-bit or 32-bit that’s the question…

I now have to decide whether to install the 64-bit edition of Office 2010 or the 32-bit edition. There’s some guidance available on Technet – 64-bit editions of Office 2010

The recommendations for which edition of Office 2010 to install are as follows:

• If users in your organization depend on existing extensions to Office, such as ActiveX controls, third-party add-ins, in-house solutions built on previous versions of Office, or 32-bit versions of programs that interface directly with Office, we recommend that you install 32-bit Office 2010 (the default installation) on computers that are running both 32-bit and 64-bit supported Windows operating systems.
• If some users in your organization are Excel expert users who work with Excel spreadsheets that are larger than 2 gigabytes (GB), they can install the 64-bit edition of Office 2010. In addition, if you have in-house solution developers, we recommend that those developers have access to the 64-bit edition of Office 2010 so that they can test and update your in-house solutions on the 64-bit edition of Office 2010.

Since I’m using both SharePoint Server 2010 and SharePoint Server 2007 (which relies on some ActiveX controls) I will probably go for 32-bit.
