Looks like an actual review of the tablet is now out (and came out a few days ago -- sorry if this has been noted elsewhere already); note that it is in Finnish (but the Google translation seemed mostly readable):

The reviewer finds that the tablet has sufficient processing power (he/she compares against the Jolla phone), a decent screen (but not quite as good as the iPad / Samsung competitors), decent battery life (better than I had expected), and pretty awful cameras .

Apparently, the most significant issue the reviewer found was compatibility with Android apps. Perhaps due to the Intel processor (I wasn't quite sure on this point) many of the apps are not able to run. So, something to beware of if you are intending to use Android stuff on your tablet...
