- exact timing (the GPS time signal is quite good, the system should be able to synchronize to that)
- automatic time zone correction – if you know where you are, you know what timezone you’re in
- integration with address book (how far am I from a specific address, what’s the closest address in my book from where I am, ideally sorted by categories)
- contextual todo lists – what things do I need to do if I’m at home/at work/close to my normal supermarket/next to a train station
and that’s only just the start.
Is anything out there that can do that already?
