Nook eBook Reader - Kindle Killer?

I still have a hard time seeing the e-reader as more than a niche product for now. For me, it is just too specialized a device. If I am going to carry something around, I want it to have full capabilities. I think the sweet spot will be when the e-reader is just a specialized netbook--one with a form geared to reading, but useable for general computing. One key might be a built-in virtual keyboard, with the option of course for a plug-in or wireless, for home-bound usage. So the Nook sounds like about a 1/4 step in this direction.
