How will pro apps adapt to the (rumoured) iPad Mini?

I don't own an iPad or any tablet for that matter. I'm a "struggling" student and worry that opening myself up to owning and relying on yet another form factor for productivity and work will end up costing me money and time when I can get by pretty well with a decent laptop and phone. At least I'm going to keep telling myself that until I burst and spend all my money on an iPad.

I'm increasingly interested in the pro apps on the iPad. They look incredibly useful and powerful. For me it's the audio apps for music performance and creation that catch my attention, but I can see that many people use pro apps for different work and study purposes.

These apps have heaps of functionality and their UIs are, from what I've seen, quite dense compared to simple general purpose apps.

My question is to iPad owners, and it is this:

How do you think dense pro apps will adapt to the rumoured 7-8" screen of the iPad Mini? If they are just to be scaled down do you think that their finer functions will still be useable? And could you imagine using the pro apps that you use for work/study on a smaller screen? Or do you think these apps will need to be overhauled to be useable at all?

If there is an iPad mini I really hope it can be a functional tool for more than just reading and watching movies. I procrastinate enough already dammit.

I'd really appreciate your thoughts!
