Are these server machines or desktops/notebooks? If the former, there
isn't really any compelling reason to avoid the 64-bit version of the
distribution. On desktops, there are occasional gotchas with 3-rd party
add-ons for your web browser and other "creature comfort" nuisance level
things. But those are mostly resolved at this juncture. I had problems
on a few desktop machines with various firefox plug-ins so I reverted to
32-bits and the problems vanished. I haven't revisited the problem
since 5.0 was released so maybe things have gotten better.
Best,
