I don't think there are many CAD artists at Fox news which was what I was getting at, i'm sure they have their use in industry, however for news research I think they are a teeny bit to big don't you?
Even drawing on something that size using the touch screen would be difficult and painful after a while I recon. Cant imagine something like that would be a daily use item, using it to view complex drawings however is another matter, you wouldn't really need the touch enabled then as the diagram/draft would be large enough to view all the detail anyway.
