Opera 10 offers Turbo mode, which sounds like something that might make my surfing from home even more pleasurable. I haven't downloaded the beta yet, though.
the turbo feature is browsing trough a Opera proxy server, which will download the content you request, compress it and send it to you. usually the compressed page is 5-6 times smaller then the normal page.
this will help a lot users with slow connections. anyone who uses Opera Mini knows
You clearly have not seen any publically released market share data for browsers.
I have read, I believe on the Opera blog, that Opera is popular in Europe where more people use older computers for daily activities. Opera is noticeably faster than IE and Firefox on the UI end so it makes a good choice for them. Web market share graphs are more likely to target english-native-language countries.
