i was switching between the beta version of 2 and the more stable version 1 it for about a year. Aesthetically it's gorgeous, the full-page view is amazing for reading text based web pages.but quitre a few web pages didnt load well, and i had the feeling that the development was drying up, the shiira homepage hadnt been updated for ages and bugs werent getting fixed. The new safari has implemented (nicked?) a crapload of the features that made shiira unique. But if the development picks up it would be the best browser yet.
