I went to a Chapters outlet and they exchanged my ARC for a new one.
The staff at the local Coles outlet were very helpful.
Have been very busy so have only had a chance to download some apps and side load some books, mp3s, and movies to try. So far the speakers seem to be working, but have only had it on for less than an hour.
Hopefully I had a lemon and will have no further difficulties.
It would be nice to get rid of the Discovery bar though. I do not do Facebook, twitter or any of the other social media, so will not be chatting with others about books. I will decide on what books I want and DO NOT WANT TO BE PESTERED AS TO WHAT SOMEONE ELSE THINKS I WANT.
