I think you are missing something
I can see great appeal for a device like this for both home and business.
Another commenter has already made the business case.
On the home side there may well be more appeal. I know loads of people that do nothing other than consume content. They check their FaceBook account every four and a half minutes. They watch music videos on YouTube. They read web sites. A device like this would be great for them. I can think of people that could throw away their laptop in favour of a device like this, and not lose any functionality.
I don't think this is a device for "those people" or even so geeks (although I'm very impressed by the concept and could think of many advantages a device like this would have for me). Geeks tend to create, and want control and speed. They want Photoshop and Visual Studio and their shell.
If you're looking for a market, you can start by looking at pretty much everyone that owns an iPhone or an iPad.
