i think what your looking for is called an iphone. i think choice is awesome.
I personally would be already happy to even see a properly working OVI Store first.
You must take into account the interests of ALL stakeholders, not just your own. Commercial app developers (and thus Ovi itself) will NOT be happy if they get competition from Free apps. You might not care, but they do. At the same time Free app developers need Ovi like a fish needs a bycicle - you expect people to pay 50E per year, give up donations and accept restrictive licenses and liability just to be able to do what they are doing now ? So, what's your plan to overcome this fire/water divide ?
I think the App Manager is perfectly fine the way it is.
