if I'm not mistaken, it's because of slower internet speeds in Belarus and Opera is pretty nice in the respect to having your browsing done on Opera servers and the response is archived and sent to the browser directly, saving some time and money.. but most people are not OK with this from a privacy standpoint in the US or Western Europe
That's Opera Mobile, the mobile browser in pre-smartphone era. The desktop version is a different product that works just like any other browser. It used to be the "fastest", like chrome is "fast" today, but I believe it has been surpassed by Chrome in this regard.
EDIT: Someone else also pointed this. Apologies for multiple posting.
No. Opera Turbo was and is still a very desktop feature, and it does significantly speeds the browsing experience. They have moved this convenience/feature over to their mobile offerings.
Opera Mini is the pre-smartphone browser (Very good IMO)
Opera Mobile is their Android offering (Very good IMO)
Well, my ISP provides 100Mbps Ethernet semi-unlimited connection for about $20/mo. (Though, it doesn't even cover entire capital city of Minsk.) And semi-/fully-unlimited ADSL connections at speed of 5Mbps cost around $10/mo. Not so expensive, either.
3G internet is a different story, though, my carrier provides 3Gb data plan for $10/mo.
It's just that for people with average salary of $500, it might be costy.
