I tried the first couple versions of Dolphin and wasn't really feeling it, mainly because the UI was a little odd to me. But Dolphin 2 cleaned up the UI a bit.
To be honest this is my favorite part of Dolphin, being able to keep the notification bar. If the stock browser could do this I wouldn't be writing this.
My second favorite feature is the grouping of the Google Services.
** New Menu 2.5 ** Old one here if you want to see the
progress.
Tabs look a bit better but they are still ginormous. But you can auto hide them.
Tabs 2.5 New and cleaner looking. 2.0 tabs screen shot

Unfortunately they did include adverts in this version. But only in the Dolphin home page. You can pay to remove them, just not quite sure that I'm ready to... My location doesn't seem to show up in Google, this a small bummer and I really don't use all the social stuff they have included. I wish someone would mod the original Android browser with the some of the small UI tweaks Dolphin has implemented and it would be a world of difference.
Anyway I will stop babbling :P
