i just recently purchased the iPad Mini 4 (64gb Space Grey) after having the iPad mini 2 for a couple of weeks (16gb, not enough. Decided I liked the mini and to invest in a new one). Right now, they are both running the latest software update BUT in split keyboard "mode" the keyboard on the Mini 4 is significantly smaller than on the Mini 2. There are no settings for the split keyboard that I can find. Has anyone else noticed the size being reduced?? It's quite annoying. It almost feels smaller than an iPhone keyboard.
