On the side of saving time (vs money), wow! I tried the Puffin browser on my iPhone today and it loads pages so quickly! I think I read that they use big data infrastructure and caching and that’s how they do it, but I am not positive. Give it a try and see if you’re blown away or can find any downsides. (Stale pages?).
You can try a free trial version from the App Store. I think it’s also available for Android devices and PCs.
It also allows for Flash multimedia content, agent changer, and many many other usability features.
