Yes, it was apparently deleted for some reason. He basically said that the Airport Extreme was completely revamped and updated to 802.11ac recently --it was in fact introduced last June at the WWDC--, and that it was a good time to buy it, to which I responded with my suggestion.
I'm still not sure why it, or even the Airport Express, do not show up in the MR buyers guide --the AppleTV is in there--, but that's another subject.
Bottom line, for less money, you could buy a router and an external HDD, but if you're planning to stick with Apple, it's a great all-in-one, set it-forget it solution.
