Thanks a lot for your important answers. I read it attentively.

Yes, Jolla is nice, I know) I saw some its reviews. It seems similar as Meego, isn't it? But why they basis it on Meego, not Maemo? I think it would be so nice...

I saw something about Blackerry too. But it seems looks like a Meego for me too. Is there are differences from Meego/Sailfish? I can't see it)

And I'm dig on Windows Phone, it looks so cool. Is somebody have an experiense in its use, is there is a sense to change Linux to Windows?

Thanks!
