(B) Granted there isn't a LOT of data here, but reading in any forum about the 7" size and you will see plenty of defenders. Secondly,
here is a MR poll showing 55% yes to 7". Third, Kindle Fire has sold millions and it doesn't even have a decent processor, app store, or user experience. (And all the stories about the infamous drop-off in sales turned out to be incorrect.) Fourth, to believe an entire customer base of that size, a size that will exceed that of desktop PCs, only wants 10" is extremely limited thinking.
