Right now I have a 2GB miniSD in my Nokia N800 (with adapter) that works great. I am going to buy an extra 8GB SDHC to add storage to my device. I know that other people here are using 8GB cards with the N800 and I was wondering what the best brand and type of SDHC card was to buy. Right now I am trying to understand the differences between this "class 6" card and this "class 4" card. Thanks in advance!
