I am going to get a MicroSD card for the Nook Color. I believe the max supported is 32 GB. and it supports MicroSD HD.
I've got about 8 GB of MP3's
I might put a few GB of pictures as well
I plan to subscribe to 1 or 2 magazines eventually (if prices are reasonable - should be cheaper than print version)
Do you think it matters what class card I get for this type of application on the NC? IE, class 4 vs 6
