I'd like to mention that if using the desktop applications such as MS
Word, Excel, Powerpoint, email software, Acrobat Reader, etc. is
important to you, then the Mac may be a better choice than a Linux
box. Mac OS X lets you use all of those, and also work at the unix
level, side by side and simultaneously, on the same machine.
On a Mac you can run R either with a GUI analagous to that of R for
Windows, or you can run it as a command line app, as on Linux.
I can't help with performance comparison questions, or the 64 bit
issue, I'm sorry to say.

A server might have other users using competing with you for cpu cycles.
A server might have a more reliable backup policy (or might not!).
A server might or might not have security patches and OS upgrades
done more promptly.
If you need to transfer content from R (text output or graphics
files) into reports or presentations,
it might be easier with a local machine, depending on whether the
server shares file systems.
