Interoperability
I wish some of them could act as Google did in the US spectrum auction; i.e. pledging a whole bunch of money on condition that all participants have to accept interoperability no matter what.
It may be just my opinion, but I think government regulation about minimum interoperability is coming no matter what. There are just not enough players to guarantee a fair competition. If so, the sooner governements force interoperability, the better.
