Welcome from Bellevue...at least I am not a 206er.
I have to agree with Vick, a 90 mm lens is pretty wide. It works well if you are doing interior architecture; however, for landscape it is hard to isolate subjects you want people to look at. For people such a wide angle lens tends to distort their appearance. 150 or thereabouts is pretty versatile.
I would predict that you will want longer rather than shorter over time.
