Sometimes a "product" or "service" is condemned... hope the best for your products and ideas general...My thought (not always right) :
Don't think so much of about such perfect idea will come out.
I believe many successful businesses are not come from a great idea.
The founders may came out with an idea which is not obvious.
It may seems not interesting or anyone can get it.
This also caused not many people will even want to invest on it in early stage.
With perseverance, the founder will keeping fine tune the product.
It is until certain versions when the product is starting to show something the public can see the usefulness.
So I can say, stick to something we are already familiar with. It is less risky and we can sure we can do it very well.
In the meantime, a problem will suddenly float up and this is the opportunity to provide a solution.
and Sometimes the same product ...comes... the most wanted... from nowhere...
Sometimes Keys / Marketing can also help a product.. can be a simple or something that someone can find it and may be find a better version from other developers... but yours can have the best "Name" / key ever.. and downloaded by Millions...
Also something... I ve seen all years I am having my own business... is that you can have 99.99% failures... and when the 0.01% you can make your turn... but need careful moves every time...
