Hey, I'm finally looking to bring mobile data to my iPad and I was wondering how far 2gb would take me for simple Internet browsing? I wouldn't be watching youtube videos, just checking up on blogs like this and engadget, some news sites, and reading some textbooks online. Pertaining to the last option, I cannot find an e-reader who supplies my college textbooks, any students replacing their books with the iPad through some avenue to buy and download them onto it? Thanks for any help.
