I realized that my data overages are mostly due to tab reloading in Safari (on both my iPhone 5 and iPad Mini). I'm on a 5GB/mo. plan, but consistently go over the limit by 3-5GB each month. Tabs reload almost all the time, and I use them a lot. So, I'm paying somewhere around $500 extra every year "thanks" to Apple putting in a measly 1GB of RAM. Does anyone else smell conspiracy here?! That's hundreds of millions, if not billions, of our hard earned $$, landing in the pockets of some people in the know at Apple and cell companies.
