1: great excuse for a pure waste of electricity. The point of a tablet, and I mean the only point of a tablet, is to be an always-on internet-connected (when in range, anyway) piece of glass to watch YouTube videos and read newspapers on. If the only time you can use it is when it's connected to a charger, it's useless. Might as well just use your computer with a bigger screen, a proper keyboard and none of these bugs.
2: clearly the issue has nothing to do with whether the applications were Android applications, Sailfish applications, TMO opened in a browser or top running in two terminals. If it did, the problem would be even worse, because the tablet is sold with 'support for Android applications'. If you can't run Android applications without the device instantly committing harakiri, it doesn't actually support anything. At least now you/I can just say the device doesn't work.
3: my point from 1 stands. Even if you only want to use your tablet as an expensive way to show off your elite Python skills, you can't show off anything if all applications are constantly crashing, and when they've finally stopped crashing the battery is dead. Did I mention you can't lower the brightness below twenty thousand lumens? The device sometimes crashing and somehow leaving an actual screen burn in? Did I mention none of these problems were ever present on the Jolla phone (besides the TOH battery draining bug in the very beginning)?

I got a Jolla phone knowing there would be plenty of bugs and forever unfinished features. I got a Jolla tablet expecting slightly less bugs and unfinished features - after all, two more years of development had already passed by the time of its release, and another one by the time I got one. Oh, but I was wrong...
Still, I will keep it, if only to have a reminder of what could have been. Maybe one day someone will fix one of these crazy bugs, maybe not. I hope for the best and fear for the worst, but then, the way the tablet currently works (or, perhaps more accurately, doesn't), this is already the worst case scenario.
