I'd like to know whether or not web browsing in particular is a sensitive activity with respect to data usage on the iPad. If there's anything that I'd probably be spending the most time doing on my iPad, it would be browsing the internet. My question is, does browsing normal websites (up to 300 - 400 a day) eat up a lot of data? I know activities like streaming videos eats up a scary amount of data - so I'll be avoiding doing that.. but what about browsing the web? Is data usage measured by how long you're connected to the web? Or by how many pages you've visited? I'd also like to know, do non-internet based applications eat up data at all? For example playing angry birds, using the CNN application, paying/checking bank statements through a bank application etc.?
