I don't think VT is available in non-64-bit mode, so you'd probably want a 
64-bit kernel and a 64-bit version of your virtualization software, if it can 
make use of VT.

For word processing, the extra registers could help, but the CPU will be 
idling mostly anyway.  So, you won't see much benefit and your word processor 
will take up some more memory. (64-bit pointers vs. 32-bit pointers -> All 
programs take some more memory.)  Even if all you did was word processing, if 
you have more than 3G of memory, you'll want 64-bit so you can use it all.  
(PAE is much slower by comparison.)

Yeah, I've been amd64 since 2005 and I never had a chroot.  Non-free just 
isn't that important for me -- I avoid java, flash, skype, google-earth, etc.

Flash has a 64-bit plugin now, although I use gnash.  OpenJDK and associated 
projects should give us a 64-bit plugin soon, if not already.  I have no need 
for skype of google-earth with ekiga and marble being available.
