Tried this a while ago (when the EU browser choice thingy for Windows was released, lol), but it seemed like the worst of all three worlds.
GUI is worse than IE6, very slow, add-ons/extensions only worked when using the rendering engine the plugin was made for (this is pretty much the only area where the Lunascape concept even had potential to do something that would justify it's usage), the list goes on. And IIRC it was slower trying to change the rendering engine than just launching the correct browser myself.
So no thanks, I'm gonna keep using Chrome for now, thank you very much.
I don't notice any speed difference because everything seems nearly instant to me. I guess I'm too patient to care about that 0.01 second difference.
However, the acid3 test shows that chrome takes longer than normal on some tests.
Note however that just because overall Opera might be faster doesn't mean that it's faster in "real applications". For example "html5 games" are often optimized for Chrome.
Does anyone care? This isnt a browser wars thread
It is, in a way, since it's about a browser. So arguing something vs Lunascape would be on-topic. So, Chrome vs Lunascape would be on-topic while Firefox vs Chrome would be off-topic.
