If OWB is faster, then wy netsurf is a google summer of Code projecrt since 2 years and there is no OWB Version in a Linux distri ?.the big disadvantage of netsurf is currently missung java script but its in Linux Distri.
netsurf is in Linux distri.Wy not OWB ?
Because OWB is a Sand-Labs project initially dedicated only to CE device and it was/is builded around WebKit, you didn't found it on Linux yet just because they are use a more complete core or complete browser around the same WebKit core
Having said that you can't compare it with NetSurf that it is actually a "spare time" project maded by a little and passionate community, mostly RiscOS developers ...
As Fab say actually OWB on OS4/MOS are MUCH faster than any NetSurf release and it is constantly updated.
What I like to see (maybe one day) is a MUI version that can cover all the Amiga like systems, expecially for AmigaOS 3.x, that because when OS4 Reaction class are constantly updated, 68k class not :-)
P.S.
I'm a NetSurf 3.x betatester on OS4 so I know very well what I say ;-)
