iPad Test Cards

[Gerz]

I read with interest thread about knee board with rolling paper.

I am interested in an iPad based test card scheme. Features that would be cool:
1. Use stylus to write note.
2. Internal iPad clock could be used to record event times and "Hacks."
3. Internal GPS could give acceleration?
4. Availability of Ground Speed?
5. Voice recording feature?

Thanks,

Gerz
