2-3 gigs a month.
I have my pod casts set to dl over WiFi only, do this at night at home so the next day they are good to go.
I don't stream anything other than the rare Netflix, I do watch a bit of YouTube.
A lot of web browsing/forum cruising.
I usually keep 4g off, really for anything other than dl large files (roms ect) or streaming a movie is unneeded and 3g in my area is good enough, YouTube rarly buffers, tune in radio doesn't skip a beat.
Better battery life is more more important for me that a little speed increase.
