i've used opera mini a lot. on dumb nokias, even on an iphone 3g and android. the built in rss reader and data compression made my 50mb quote of data on pre pay 15 years ago go a long long way. i could browse the web all day using rss and text only sites.

when it was taken over by the chinese the rss went away for a few years but it did come back. when stuck in hospital for a few months over the last decade it kept me from boredom.

now that my dumb nokia can't do data i do miss it. last time i was in hospital i used an rss reader on android on hospital wifi. just wasn't as neat and easy to use. the dumb nokia was meant to be used in one hand. android and smartphones need two hands to use.
