I love the Kobo because it allows me to obtain books from a variety of sources, including my old Kindle purchases. Funny thing is, I never want to be stuck in a closed ecosystem again. But the reviewer is right, the Vox is less polished. Kobo needs to integrate borrowing and PDF support into their own software. That would merge three collections into one for most people. And, of course, they need to address tge many small bugs that plague the critter. Then there is improving the rest of the system by addressing the less critical stuff.
