Ok, so i'm wanting to do the following and wondering if I need to keep as is, root, or put new OS completely on. 1. Read books 2. Read PDFs 3. Browse net 4. Watch videos 5. utilize apps and emails I'm just concerned about the rooting and putting new OS on...will i lose the normal Nook features? I would like to be able to also use the SD card as an actual storage device, so not sure if while Rooting if i can actually do that too? Any help would be appreciated!
