Agreed! I don't know why these companies don't seem to understand that is we are buying these devices, we will most likely buy the accessories too!
It's like they don't want our money! :-$
I am still waiting for a dock for my Nexus 10... it showed up in a holiday video, but never materialized past that. I even went third party for the pogo pin charger. I mean, why put the pogo pins on if you aren't going to supply a charger?
We usually don't have a choice but to go third party, and then IF an official OEM item comes out, we have already settled and most likely won't buy at that point.
I am with you and hope these items are available soon!
