Worth a mention.

It installs separate to the old Opera Mini.
My first impression - like lightning - data saving 96%

I found it had problems with some websites. Could not be bothered with it. Chrome is much better.

Well I'm using a Nook HD+ c/w a paltry 1GB Ram. There is no problem, even with a dozen tabs open.

I certainly can`t say that for Chrome, even with an invite to test their data compression!
