Does anyone have any experiences with touch screens on Myriad?

We are considering it for 'user friendliness' reasons.

I don't know if there are any particular restrictions, recommendations, or requirements from Myriad to do this???

Any favourite / least fave manufacturers?

I seem to remember someone at P Squared saying that they didn't recommend it though!! (too easy to make a mistake or something??).
