I finally got our new solution for NAS setup today, using the Apple time machine. As we have the current imacs using n wireless, our existing wireless router was only g wireless. Wireless was good, but what a difference switching to all n wireless. I now fully understand how the new apple tv works so flawlessly, with no stutter or lag... amazing difference. I expected a boost, but the increase blew me away. This is true LAN speed over wireless.
Impressive stuff... now I know what others have told me I was missing.
