Interestingly, a similar post in FT quotes Noury as saying that eReaders are suitable only “for the upper class, people over 45, big readers, big travellers, early adopters.” First, aren't these people his primary customers? Second, if that's his attitude, no wonder he's worried. The man is in denial.
Let's look at another post on Teleread. A Sony owner who goes by the moniker Ficbot posted a piece about his/her ebook buying habits. Ficbot likes Ficitonwise (I do, too. It's very Kindle-friendly), Baen Books, and Smashwords, and is exploring ereader.com. What's clear is that Ficbot is shopping by looking where ebooks are available, not by looking at bookstores or even book review sites. That's because Ficbot wants ebooks!
And a main rule of retail selling is, you have to give people what they want, because if you don't someone else will.
Addendum: case in point— Apple just confirmed an iPod event for September 9. Everyone is guessing they will announce an "iPad" (large screen iTouch) that will, among other things function as an eReader. It will almost certainly be snapped up by the upper class, traveling, reading population over 45.
