I use my 64 bit system as a Boxee/Hulu/Xbmc box, but after having flash issues 
I swithed to 32 bit

I have 4 gb ram, so the installer automatically installed the pae kernel that 
provides 32bit systems the ability to use all the ram

In a normal 'buntu 64 bit system, it is utilizing the 32-bit binaries using 
the nspluginwrapper to allow flash to work in 64bit systems. I found this to be 
a problem on my system trying to run Boxee, even using the the-available 64-
bit flash from Adobe.

for the use I am making of that system, I cannot tell any difference in 
performance, other than stable flash
