I'm not sure I understand the way these data plans work. There's 1GB, 3GB, and 5GB plans... but aren't these extremely low? Wouldn't the average user who watches shows on netflix and games go through this in a couple days? Surely I'm missing something here... perhaps they calculate the data differently?
I have 6GB on my iPhone 4 and it's way more than enough. I'm on wifi most of the time (home/on campus). Think about the times you will be without wifi access and using your iPad for data heavy usage.
