My Galaxy wasn't retail.  But that was a pretty narrow opportunity.  ;-)

I'm very interested in a Honeycomb Nook color also.

*OLED displays have a pop that is very hard to get with transmissive LCDs.  If it is LCD, it is the among the best I've ever seen.  
The 7" Galaxy is definitely not, but this is the not yet released 10.1.

I was referring to the whole package.  For instance, nobody else has a bluetooth keyboard (Motorola has one close, but doesn't sell 
it separately) or mouse or desktop box like Apple.
Here, there's nothing obvious that's better about an iPad 2 vs. the Galaxy Tab 10.1, as opposed to comparing it to a Xoom.  Except 
for the magnetic leather cover.  That's somewhat surprising.

Yes, but something more than what has been implemented in production devices so far:

Should be very cool, but will take a while to get there.

In a lot of cases, Google and/or the hardware vendor require that rooting is allowed.  When the phone providers are involved, they 
seem to insist on preventing it for phone devices, but are apparently more flexible for tablet-only devices.  I'm guessing this 
indicates some bad hacks are possible on a rooted phone.  Motorola specifically said at AnDevCon that their tablet devices would be 
rootable for development.  Google specifically mentioned the Chromepad will be rootable for dev.  Unclear about GoogleTV, but I'm 
pretty sure that will come with the addition of Android apps.  They have to have adb access to have Market apps, a rule apparently.

Yep, I think so.  It seems we'll have 16 core ARM, and even more impressive GPUs, in a year or so.
