Edit: rms is right. How about "If someone paid you $1 billion with the condition that you could never do anything productive ever again, and basically had to live a playboy's life forever, would you do it?"
Edit: Revised question is really interesting. I don't know what my answer would be.
Also, I think there is such thing as too much money. In terms of happiness, money provides diminishing returns. I believe that having enough to not worry about having to generate income is a good goal for most people. Beyond that, it can create a feeling of alienation with regards to the rest of the population, as you would be too far to the right on the wealth distribution curve and would have few peers. What do you get in return? Fame (if you want it) and access to extravagant toys. The real problems in life remain the same whether you have 10M or 1B: you will get old, you may have family or health problems, accidents happen, etc.
Alienation + productivity ban = sad life. No thanks.
Definitely no.
What "can" you design under $1 that solves a major problem in the world?
Example answer: packets of salt and sugar is all it takes to prevent/solve dehydration in many sub-saharan countries. Can it save the world? Yes. Is it executable? Yes. Is the UI simple? Yes, ziplock sugar packets. Marketing costs? evangelize.
Point is that the technical skills can be evaluated to a great accuracy more or less, it is the real-time thinking skill that matters; i.e. it is extremely ok to ask a question that demands considerable attention and problem-solving. An ideal interviewee knows that a good answer is not a matter of complete polarization, but careful articulation.

With all due respect I wonder how many successful entrepreneurs (Steve Jobs for e.g) would be able to answer this question?
This sounds like one of those textbook/puzzle questions which sound very clever but don't stand up to any rigorous analysis( imo).
I would be very surprised if answering this question "well" (your salt/sugar answer for example) correlated with any significant measure of entrepreneurial success. Needless to say, I would love to to data or studies that show otherwise.

Again, it was an example. One could very well ask someone an on-the-spot question that would arise in a typical startup situation.
Answering the question "well" - if you are basing a hire's success just on the outcome of a question, then you may have some serious issues with measuring success.
First question: why? You guys are smart/energetic/young/etc -- why do this? Why not join BigCorp or become a priest or something?
Second question: What do you worry about the most? What keeps you up at night?
Third question: If you could only pick one thing to validate your reason for forming a startup, what would it be? In other words, what would be the single biggest indicator to you that you are doing the right thing?
2. How have you changed since you started?
3. What key skill or experience did you lack when you started that has caused you the most problem?
4. What has been the biggest surprise: what was one key assumption you made, perhaps even unconsciously, that has caused the most grief?
5. What development, event, or new understanding since you started has had the most impact on your original plan? How has your plan changed in response?
I checked your profile but I can't determine your website, where will the interviews be posted?
1. What made you first think that starting a company is right for you?
2. Was there anyone/anything who inspired you to manage the company the way you do, and to define the culture the company has?
3. Was it obvious that the company needed to be in place X? If X is not in Silicon Valley, why not? Do you think it was the right decision?
4. Where is the best source of good people for you? What characteristics are important for them to possess (good schools, lots of experience, dedication, etc).
That's it for now. I'll add more if I think of any.
How much money do you think you'll make from this (to see how they evaluate their chances and worth), do you want to sell or remain and make a salary (to see what they are building the company for - longevity or a quick flip, not that either are bad), and what do you see your retirement like?
It might be better if your core thinking and goals, match to some extent with your probable co-founder.
Having said that, the 'skill set' of the person should compliment yours, so that as a team you are able to achieve more.
When did the business model become clear for your business?
