Well Boris, you asked how many people WOULD have purchased an eDGe? I was one of those. I was still waiting for my tax situation to settle and grad school issues to resolve, but I was VERY excited about the dual book idea. I still am. I think it;s absolutely an outstanding idea for students and educators. Its potential is sky high.
In my opinion, the failure of Entourage would just be one more example of the best product not surviving in the market, e.g. Betamax, DAT audio, etc. Very sad, if the speculation is true, and it's hard not to assume it is. If it weren't, given the situation (people reluctant to recommend the product to people who are interested, people trying to sell their used products, etc.), I can't imagine someone from Entourage wouldn't step in to calm the waters.
I hate this.
