I AM FACING THE EXACT SAME ISSUE HERE!!!!!

I sent my unit to Asus Center @ Imbi Plaza for inspection because of the keyboard locking issue, they admitted that this is their product defect and they issue a form for me to do DOA (one to one exchange). They said they don't keep the stock and I need to deal with the shop (seller) to get it exchanged. I have reported this issue ONE month ago and due to stock availability, I wait until now still got nothing.

I have been calling the seller and Asus Center, both of them just ding dong me between each other. I am like working with government office now. I don't know how much time and money have been wasted for calling and waiting and at the end they still can't promise me when will the stock arrive and let me exchange.

This is definitely a very bad customer experience with Asus. It made me feel so regret to buy from them and should have gone to iPad earlier on but I like android tablet.
