I am trying to find a good microSD card to use in my Nook Tablet. I have a Patriot 32GB Class 10. However, when trying to revert back to 1.4.0 firmware version, it never lets it work. So, I am going to try a new card. Here is what I am looking at: Sandisk 16GB Class 4 (or a 32GB) Transcend 16GB Class 6 Kingston 16GB Class 10 Lexar 32GB Class 10 What are some thoughts? I would like to watch YouTube stuff, use Netflix(when I finally get back to the USA), and put movies on the Nook(although I am not sure how to do that yet). Is the Class 10 necessary, or overkill? Will the Class 4 be enough? Or is there is something better than what I have listed? Thank you for your input!
