As for not getting Bluetooth installed at purchase, it says you can easily connect with the USB dongle. You still can get the internal Blue tooth device put in but you have to send it to apple or a shop so they can open it up.
I am happy with the upgrades. I just wish the lower end model was had DDR. As for 10/100/1000, it's still to expensive for a switch or even a basic hub, and a mass majority of the networks out there, even Cat 5e and some Cat 6 networks still can't handle the badnwidth. The only time we used it was between machines and even then turning the targeted computer to Target Disk mode and copying things over firewire was better.
