I would be surprised that the new reference HW design (nCDK/iCDK) for Meego 1.2 (and up) testing would be more capable, faster than the first Meego/harmattan device (N9?) if it has an Intel Atom in the first place of course.

Never good to test UX internally on a faster design that what you're pushing in the market ... User perception will be less in the field than internally ... Not really what one normally wants, I would think.
