It is not just the keyboard connectivity and pencil battery life. There are many other issues aswell starting from how heavy or uncomfortable they are to use ending to the bad life expectancy. Those reviews just confirms my thoughs on these products, before I have even read those reviews.
This is not hating on Apple, oh not at all! More of a frustration on how bad decidions Apple is making by continuing with this path with the next iPads also.
I have to agree with your post. Until the IPP 12.9 G2, ASK, and AP, I have had very few issues with my Apple products. This version and its' "attachments" though has been a serious disappointment.
