Might it not be said that sticking the cellular subsystem into the N900 raised its profile higher than Nokia expected?
This was one of the things I was referring to. The whole Step X of 4 or Step X of 5 or whatever is a great idea... but you can't all of a sudden at step 3 or 4 just decide you want to completely redo everything. The N900 actually became Step 1 of 2.. and all of the previous steps were dropped off into a black hole.
