I'm using Opera 10 on a macbook with SL.... it's ok, but there are several occasions when loading a page stops or becomes very slow - not hopeless, but certainly annoying. It's a new macbook, so can't compare it to version 9 on which i never had any problems with on windows desktop and laptops.
Will take a look at openDNS - that's worth looking at anyway.
thanks - wish i could get back/forward site navigation with touchpad swipe..... the old 2 button trick can't be done on the big mac touchpads....
