Yep, if you notice I mentioned I'm running 32-Bit Lucid on my laptop 
with 4GB Ram...

This is on Ubuntu 10.04 Beta 2 Desktop.  I'm considering upgrading to 
64-Bit when it comes out on Thursday though as I've started a new role 
which involves some Windows Server stuff and I dare say being able to 
run the 64-Bit Windows server 2008 on VirtualBox would be handy for me.
