After reading all the comments to this point, I feel like I'm obligated to comment (not sure why, other than I paid the price of admission)
Arguing over MPGs is like the discussion I had regarding impending skylight installations in my house. The negative commentors told tales of high fuel bills, and "expensive holes in the roof". True. And so be it. I didn't build a house to have bench racing comparisons of fuel bills. I built it to make me happy. A place I wanted to live in. I like natural light and ventilation, and I'm perfectly happy to trade some cost for the pleasure I glean from that "waste".
I see trucks (vehicles!) much the same. They all get comparibly decent mileage, are reasonably pleasing to look at, are comfortable and powerful at a price most of us can afford. My subjective opinions are not your subjective opinions. I don't get all the nitpicking bordering on personal attacks.
Personally, I love my truck. Is it perfect? Hardly. But, it's close enough for me, and it beats the last one hands down ('94 F-250, 5.8). If there is one thing I could put some extra money behind, it's more power and some extra mpgs, and the Ecoboost seems to fill that bill nicely at a not-too-large premium. I don't own one, but I might some day. The power curve figures alone in conjunction with the stated fuel economy are enough to get my attention, since I already love the 150. I tow 8K at 15,500 combined with my 5.4, and get around 8-9 mpg at sea level w/rolling hills. Mountains at altitude bring me down to 7 or less. Daily combined runs about 14. Living with 11 towing and 19 not, with that kind of torque? Yeah, I'll go for that. I think they should do the same treatment to a small V-8 for the bigger trucks. Diesels certainly have their place, but someone can have mine. My .02
