To me, the design of the W890 is nicer and more user friendly than the W880 (ugh horrible number keys).

Correct me if I'm wrong but is the W380 the first SE to have the loud speaker on the front?
I like the external screen of the W380 and improves many of the features of the W300 (176x220px Screen, 265k Colour screen, 1.3MP camera.).
