Two (rooted) Kobo Vox units here and both suffer from all the bugs mentioned above.
I own a Kobo Touch and the updates and support for this device is what made me go for the Kobo Vox.
Sorely disappointed with the Vox. At this time, I can't recommend it to anyone. I'm hopeful that the Kobo team will update the software to address these issues.
EDIT : Could this be stickied? This is ripe for a "Me too!" type thread and the post-count could go some way towards convincing the Kobo people that there's lots of us suffering from these problems.
