In preparation for this reply, I just upgraded to Warpzilla 0.9.2 (was using build 022801). I've used Warpzilla for most of my browsing for at lest 8 months now, and it is quite good, but I feel Opera does have a place in OS/2, if it gets reasonably debugged. It's quite a nice brower (I used the Windows 3.1 version until it became too unstable under WinOS2 to use).

Yes, I'd strongly prefer a native OS/2 version, but it doesn't look like that's possible.
