Yeah, pretty sleek

It has to (i believe) be one of two things:

1) A very slim smartphone like the GSII/SE Arc etc which slots into the back of a (8"+) tablet. And actually the tablet is just a display + touchscreen + batteries .... sort of like the Transformer-dock or Moto-lap-dock.
Obviously the phone is running Honeycombe 3.0 which becomes activated automatically when the phone is "docked-in" ... and reverts to the Gingerbread UI when you remove it.

2) What if its just a 7" or a 8.9" tablet that does have a microphone, an earpiece and the proper voice dialing (GSM/CDMA) frequencies ......basically an oversized phone.

... Which type of device would you guys prefer #1 or #2?
