First off, what more can I saw about this ship that hasn't already been said? One thing I think they should have waited on (and nobody shoot me over this!) was releasing the AT-TE along the same time. Two HIGH ticket items at one time? I know I'll have to choose one over the other and for me, the Falcon is the obvious choice.
Now for that little fighter. I saw a video (like everyone else) that said the fighter was to give kids something to 'play' with since the ship is so big. Personally, I plan on having that spot as a cargo bay, so what do I do with the small ship?
Here's an idea: Take one of the older Falcons (that will be flooding eBay if nothing else) and modify it. Cut the current cockpit off and cover it over, then mount this little fighter between the mandables. It should give a nice new look to the ship and create a new light freighter.
You could also get one of the small 'submarine' toys and mount the gripper arms on the front of it and create a small work-bee type craft.
I'm sure there are lots of other uses for this nifty little feller...
