I'm not buying the excuses as to why Apple couldn't utilize a smaller screen. They design the hardware and write the software, they can do anything they want with it, including things you've never thought of.
An iPad w/a 7.85" screen in a 4:3 format would have these dimensions:
29.5788 sq inches area
The kindle fire has a screen size with the following dimensions:
20.923 sq inches area
The width won't increase much (0.18"), but you are gaining over an inch in height (yes this is all in my head in landscape mode) (1.28" to be precise) and 0.85" on the diagonal which lets things be much more spread out. Apple clearly experimented w/smaller screens and decided that the 7" format was a bit too cramped for what they wanted to be doing on an iPad. 7.85 adds nearly an inch to diagonal, giving us a total area increase of 41% over the 7" tablet. Just go using 4:3 instead of 16:9 and adding 0.85" to the diagonal. That is a significant increase. The difference in surface are for teh screen of the 7" Fire compared w/the 9.7" iPad is huge.
EDIT: Just for fun, here is the iPad dimensions based on screen size
40.22 sq inches area
Note the iPad screen is just shy of double the area of the Kindle Fire. It's just over 1/3 larger than the proposed 7.85" screen.
For those interesting in the math to figure dimensions w/only a diagonal measurement and aspect ratio, here you go:
(stolen from: http://forum.onlineconversion.com/showthread.php?t=7230
For a 4:3 tv, the height:width:diagonal are in the ratio 3:4:5. So the height is 3/5 x the diagonal, and width 4/5
(or 60% and 80%).
For a 16:9 tv, the ratio is 9:16:sqrt(337). Height is 9*diag/sqrt(337), width is 16*diag/sqrt(337), or about 49% and 87% of diagonal.
sqrt of 337 = 18.357559750685819298491719518707

I don't think they would have to. They would keep the 1024x768 resolution of the iPad and the same 4:3 aspect ratio it has and then iPad apps would be the same, just a bit smaller. iPhone apps would still get bigger like they do, just not AS big
