As far as I'm concerned the LE was worth it. All in-game Halo 4 content has not been released on the Marketplace, so I'm pretty happy there. I actually like the Prime skins for the Recruit armor and Assault Rifle.
Plus the emblems were a plus (I got like 3 extra emblems with Gamestop which I'm pretty sure I wasn't supposed to get which is beside the point.)
If anyone had actually read through the papers and booklets with the LE they would have found a significant amount of information relating to Spartan Thorne (and his questions on why there is so little information relating to Master Chief), The Spartan IVs, the Infinity, and how a normal day for a Spartan IV plays out. Definitely worth a good read in my opinion. I also found out that the Infinity gives out special Community Cupcakes
Plus you get a free digital copy of Forward Unto Dawn, a cool protective case, and cool metallic game case (which I'm having a hard time getting the game to come out of).
All of that was probably worth allot more than $40 if it was sold on it's own, so the LE itself was a great deal. I don't understand why anyone would complain with that unless they just flat out don't like the LE.
