Steve Jobs, the late cofounder of Apple Inc., occasionally got it wrong; the proof is right here on my desk.
The original Apple iPad sports a screen nearly 10 inches wide. Some in the company suggested a smaller version — 7 inches or so. Jobs said no; but rivals have been saying yes, with considerable success.

Profiles sounds like a great idea; my iPad is cluttered with stuff for my kids.
Hiawatha, how can you run this comparison while only devoting one line to the Nexus 7? You have to include it for any credible comparison. Either you compare the small Ipad to the Nexus 7 or you include both the storefront tablets--Nook and Kindle to provide any sort of meaningful comparison.
