Answer

I think the teapot is

Plane

My first teapot is on the ground

A plane is a flat surface or flat area of land.

My second teapot is in the air

Plane is also short for aeroplane

My first teapot is plain

Flat planes are not very interesting to look at

My second teapot is advanced

(Aero)planes are a technological achievement.

My first teapot is unsorted

Mathemetical planes have affine symmetry so we can move them around and they look the same

My second teapot is very structured

(Aero)planes have a lot of structure to them.

My first teapot can have a promotory

A promotory is a raised mass of land that projects into a lowland (plane)

My second teapot has a nose

An (aero)plane has a nose.
