I've ordered one for myself as well.  The extra RAM will certainly
come in useful for deployments! 

If you have a setup with a serial cable, something else to experiment
with is to upgrade the version of Xen that's supplied to Xen 4.5. 
The current Xen 4.4-rc had a limitation that half of the board memory
can't be assigned to domUs, and I think that got fixed in Xen 4.5.
Thomas, do you remember the details of this?
