Maemo/Meego wasn't really an option. It wasn't ready back then and it doesn't seem to be ready now either, since rumours say that Samsung has axed Tizen development.
I think the only company currently developing Maemo/Meego succesor is Jolla with their Sailfish OS. Although they've also missed deadlines they've given themselves, so their product is starting slip more and more into to the vaporware category.
