all my earlier smartphones have been bricks eg n93 > 9300i > e90 & now n900. since i change phones only every few years i'm in no rush to jump ship just yet as long as she holds herself together. ''come on baby, hold yourself together''.
next phone's gotta have a qwerty, the usual apps & browser like n900 with open os. so yeah- no rush, no regrets.
-footnote-
i chose n900 when a next gen nokia communicator never showed. i'm really glad i did.. & hats off to you geniuses too for making n900 practical & fun!
