To the TS:
I was initially in a dilemma on whether to get the N73 (for it's all rounded-ness and the Symbian OS), and the K800i (for its camera).
It all boils down to what are your needs actually. If you are not intending to use the Symbian features, the K800i's a sure winner.
Else, the N73 would be great for your needs (the scheduling functions are great!)
