Hi Sotos,
I only joined the forums a few days ago so this is my first post
I have been using the latest beta (20th March) for a couple of days now and it seems pretty stable on my PC and all of the sites I normally visit open and display ok.
My first thoughts are mixed, the displayed fonts seem clearer, particularly in forums like this one and everything is there, just in different places but the RSS feed looks as though it could be useful, however, overall I'm not sure that it has been worth it. I will give it another couple of weeks and see how I feel then.
