What's the biggest difference? No overhead bins! It looks positively roomy in there.
I wonder if the overhead bin model is really the best one -- it feels like a huge bottleneck. Reduces headspace, slows down load in and load out dramatically since it essentially requires that every passenger be able to military press a 20lb+ weight (or have someone else do it).
I'm not sure what a better plan would be though :) Maybe raise the cabin slightly and have the bins be built into the floors below each seat?
