Hi,
what do you mean with "I do loads of ppt"?
Do you prepare them for yourself, for someone other than you?
Do they get shown on a projector from the ipad or from a desktop, or on the iPad only?
I do a lot of ppt, too, and I present them with the keynote app from the iPad with a projector.
To see the notes while the audience sees the slides I have an iPod touch and use keynote remote app.
Hope this helps.
