Hmph. The assumption you could run Ubuntu on it is not necessarilly good. Obviously I'm just speculating, but to me it seems a lot more likely to be (as suggested by the linked article) an 800x480 or so iPhone-like device, so non-x86. Hardware-wise, I'm not seeing any real advantages over a Pandora or N9xx, and very little over an N8x0. Considering the likely cost difference, I'm unlikely to be interested when it is released.

If, otoh, it turns out to be the long-awaited MacTablet or UMPC, it'll just be another sweet piece of hardware with a bit too high a premium for me.
