I think it's because they won't be able to get moneyca (Get it?) from it. Lets face it, Not everyone wants to make Apps for free, some do, and i love a free app, No lies there, but some want money, so developers are thinking, Nokia closed the official store, So developing Meego apps means , almost no money for them. this is not appealing to everyone.

Plus i would think you would be able to put Meego On Samsung GS2 because they used the same Kernel as Meego, with differences, they both used a Monolithic Kernel, with a few alterations Googles part, so it should not be that hard to port Meego to an android developed device but for the amount of work, some developers would not see it as worth it. Seeing they will not be able to have a steady relationship with Moneyca (Did it again LOL ). My opinion anyways.
