So I think over a class 4 or 6, after reading the forums, I've decided that a class 2 is probably enough to do the trick. I'll just be using it to watch some movies and listen to music -- and am not really concerned if it takes a bit longer than a class 4 to copy music to the card. With the price difference not being major between a 16gb and a 32gb, I'm looking at a 32gb. From what I've read, both SanDisk and Transcend are very legit companies. Anyone have better/worse experience with one over the other? Also, I once had a very bad experience using a large memory card in a BB (stuttering, etc.). Is there anything to the idea that a 16gb might function better with the Evo than a 32gb would? And just to further complicate things... Would you do a 16gb class 4 or a 32gb class 6? Thanks!
