The other thing is that many people use tablets as their ebook readers, rather than standalone devices. The innovation is tablets has been pretty strong since 2012.
I would say that where the biggest change since 2012 has been the speed at which ebooks are becoming the norm. Very few new books are not available as ebooks and a ton of backlist books have made it to ebooks. We still have a long way to go before we get to the point that every book every written is available, but compared to 2012, it's pretty amazing.
I still say that the next big jump will be software, both in finding new books to read as well as organizing and reading the ebooks you have.
