builds 3 and 4

my first two builds of windows 7 in one way brought me back to when windows vista was in beta (downloading the bits, burning dvds, waiting while the installation runs), but since windows 7 is building upon the foundation that windows vista sp1 and windows server 2008 created, it's been a process i'm now very familiar with and appreciate that i can kick off the build, walk away and have a couple final customizations before using the system.  so i'm taking the plunge and building out more systems - i'll also try and track my 64 bit versus 32 bit experience(s), but more and more i'll be spending my time in the 64 bit version.
