I don't like the idea of stuff popping up asking me to launch programs. I have enough problems with the N900 constantly being at the limit of its capacity and stuff slowing down.

If I don't know how to get somewhere, I will open the Maps app and find out. But only once I'm already going. I'd rather have everything moving at my pace instead of me having to estimate days in advance how soon before the event I need instructions to get there.

My only wish is, that you could add street addresses to contacts and see the contacts marked on Maps automatically.
