I remember when I first got my iPhone (it was a first generation that I had to unlock to use outside of the US), I was very amazed by the syncing capabilities. The data on the phone was exactly the same as on the computer, I could copy all my bookmarks, e-mail account settings and my entire phonebook without any problems such as duplication or the phone simply not syncing (I used to use Sony Ericssons). However I was, and still am, intrigued as to why the phone cannot sync tasks or to-dos. The reason is very simple; Leopard has it and since it could sync everything over from the computer, why not tasks and to-dos??
