I understand what you are saying, however, the average user probably doesn't even understand what Unite is, or will ever attempt to use it. As far as Opera the browser goes it has been on all my computers since 2001 when switching from IE 5.5. In fact I started using 10 when it was still in Alpha mode. IMHO Opera is the best browser I have found—now that not saying anything against the others; to each their own.
And, as far as Unite goes it will probably not see the light day (or the dark of night) on my computer. Like you all I see is a nightmare waiting to happen.
