if your on a 30-45minute bus ride, are you going to be stuck on 1 page?
If you enjoy reading, you can easily go through 10-20 pages of articles/forums etc in 30 mins.
If you save 10secs per page load, that is an extra 3 mins you get to read one more article/page/...
Sounds AWESOME!!!
Wait... you were complaining about this, yeah? Or thinking that reading a single extra webpage per 45 minutes is somehow going to affect your data usage in a noticeable way?? lulz
