everything a desktop computer does is RAM-limited (this is even true
for most CPU-intensive applications), so using a lot less RAM really
does help.

Moving to full 64bit should indeed be a better choice, you would
think, yet many of apps & plugins are still 32bit only.
I believe that this is fluff and not fact. There are a few apps
which only have 32bit plug-ins for certain capabilities, ie: I still
run 32bit firefox and plug-ins and 32bit java. But *everything* else
on my 10.1 system *is* 64bit.
