Hello. I have this tablet arriving, the 7inch version. Does anyone know about this - plenty of reviews says it lags a lot, how true is that and can a fix be expected from Samsung (I don't really trust Samsung, a cheaper feature-phone I have of theirs provided a pretty poor experience in terms of performance, touch responsiveness, etc,. Someone else got this tab.) ? Will I be able to load the future Ubuntu Unity phone ui on it? What other software ROM can I load on it, will Meego's successor, Sailfish/Jolla boot on it? I also have this weird desire to run Gnome Shell on it. Is that possible?

Thanks.
