You are right but you forget one view:
When sombody whant it at home, he can place one or many BT accesspoints
in his apartement/office/house :)
Ok Dect/GAP would be better....

Being on the road, I know WiFI access points, but no DECT station where
I could log in...
Also friend of mine would may give me internet connections via  Wifi/BT,
but using their DECT (when they have one) to doing ore getting calls 
is too complicated.

So focusing first on solution for cheap internet/data connections/voip on the 
road outside the living room worth it - IMHO. 
On the long term are you right, Dect/Gap would be smart to have it in
the phone ;)

So back to my question what would be more power efficient on the 
mobil - anybody an idea?
