Wow, I really hope more tablet users may convince Jolla to make some software optimisations.

As mosen wrote earlier, the percieved framerate on the tablet is really low, also parts of the glassy background of normal silica apps tend to flicker black now and then.
Also, the build in screenshot capabilities in lipstick are really only fast enough on really low resolutions (JP01), what makes things like screencasting impossible.

But – as we all know – the most important thing still missing is split screen support.
