My expectations were high but right from the beginning I had troubles.
First of all the browser was nowhere to be found on the market. Ok, no problem , went on to allowing non-market apps in Settings and downloaded it right from the web.
First run - crashed.
Second run loads a pretty sweet start page with some preinsatalled site links ala' Opera, with one extra "dice" link which is a link to a random (?) site. Couldn't change the links on this page to my favorite sites. Even if this option is there, it's not obvious, since this is also not allowed in settings.
Loading times. Using NYTimes as a benchmark I've managed to achieve 15 sec to fully loaded site over WiFi. 3G network is twice as slow.
No pinch-to-zoom and no multitouch.
Video feature is a nice solution, but while it allows you to watch the embedded videos, the loading times are slow, videos keep freezing.
Third run - crashed.
All in all I think it's a very nice browser, which renders sites as expected, and would be a good addition to your phone, but I wouldn't recommend it on Galaxy as a main browser.
