Well, I'm going to get my hands on review units of the Africa and the Bing so I'll see how they look in person. I can't speak to the Bing's similarity to the Mac, but I will note that I only heard of Bing a couple of months ago and I gather CherryPal was making its prior model of Bing earlier than that.
And I'll definitely be asking him about the components vs. job lots matter in the interview tomorrow. His blog post certainly makes it SOUND like components.
Of course, even if they are job lots and not hand-assembled, the Africa still looks a pretty good value. As I pointed out in my article linked from the OP, the closest thing to those basic specs is the Menq EasyPC (similar specs but less memory), and that normally wholesales at $80. Getting something at least slightly better for $99 retail seems reasonable by comparison.
Someone down-thread is talking about reconditioned Eee 7" models costing $100. I haven't been able to find anything like that for less than $250. And while my budget might stretch to a $99 Africa, it certainly won't stretch to a $250 Eee.
