I was thinking of getting the lowest end x4100m2.  It is not available
with dvd drive, which is fine, I would always or nearly always net
boot and I'm glad to save the extra few dollars.  Also glad to have
the extra on-board disk capacity.  But just in case, does anyone know
if this guy can boot off of a usb dvd drive?  I guess these guys also
have that virtual dvd drive redirector thing in the bios, does anyone
know if this will work using a macbook?  Being able to use a usb dvd
drive is more important to me, though.

Also, anyone know if this can be updated to dual processors and faster
processors?
