Over 3 months just to fix some bugs, improve the performance and fix the stability issues is a little disappointing to say the least!
My guess it there is like 1 programmer working on the firmware, so I'm sure they are doing the best they can, but some how I doubt kobo have put much resources into it.
Here was I expecting a boat load of amazing new features, sigh.
If the unit performs a lot better I may forgive them.
