is there actually a change in the geometry set up , or does it just feel like there is due to different tank sizes,windscreen etc.
i have had two " normal " 12's. just fancy the real McCoy?!
I had two of the budget

1200's before getting the 12ADV
It was a few months back now, and i don't regret it at all.
Pro's
Bigger tank (330mls till fill up)
Better looks (JMO of course.)
Better screen
Better panniers (metal mules)
More reliable (touch wood)
More stable to ride, (feels more of a bimbler than a scratcher. but has the feeling you could invade poland with one, sort of an unstoppable feeling the the 1200 basic hasn't got.)
Better ground clearance (see below)
For me, better suspension (when set at a suitable ride height, loaded, with plenty of ground clearance, the ride is plush, while the same set up with the older bikes would have left the ride harsh)
Cons
Heavier (esp with a full tank)
A bit slower (see above)
Too tall (sometimes)
Harder to clean (so i've not really bothered much beyond salt protection and maintenance)
Lots of them about nowadays
