I agree, without some sort of celebratory act in the line of "Jolla enters a new stage and so do I" this seems like bad timing – with the tablet and Sailfish 2.0 finally ready to go. Dillon is a very likeable guy and Jolla should see to replace him with someone of similar charisma to keep the brand moving forward.
Anyway, whatever happens next: I gladly forked out for that tablet and am very much looking forward to getting my hands on it. I am also keen to see the OS on other makers' hardware.
From my perspective, Jolla and Sailfish are among the most interesting and significant things to happen in mobile since Jobs' death and Nokia leaving the building. They are a force of positive disruption desperately needed in a market saturated to death with samey uninspiredness.
