32 bit Office 2011 for Mac users only. 32 bit version takes less system resources and does absolutely fine compared to 64 bit version.
Latest news from Microsoft Office officials is that Mac users will only be getting Office 2011 in 32 bit version only, no 64 bit version, when Microsoft releases Office 2010 for Mac this fall. Earlier, Microsoft also announced that Office 2010 will not run on 64 bit version of Windows XP.
Going by the facts, 64 bit version of Office suite has never been the preferred option for most of the Office users across the world. 32 bit version takes less system resources and does absolutely fine compared to 64 bit version.
The only difference that 64 bit Office version brings in is that there is no limit over the file size of office documents in the higher bit version. But practically, it’s a rare possibility for anyone to create word, excel & powerpoint documents of file size crossing more than 2 GB of size, even for enterprise users.
Hence, there will hardly be anyone who is going to bother about the absence of 64 bit version of Office 2010, that too for minority Mac users, when 32 bit version comes out this fall.
