I have purchased OF for iPhone (enjoying it so far-thanks!) and am currently using the desktop version in trial mode.

I like being able to work with my tasks on both platforms, but I am wondering if I can be successful/happy with only using the iPhone version. Therefore, I was wondering if anyone out there is using the iPhone version only. Or, for those of you with more experience than myself using both, what advantages do you see having the desktop version in tandem with the iPhone version?
