The only thing I care about with the new Steam is having to click twice to get to my games. I'll try that one thing and tell you if it works Kavinsky.
The one positive thing about this though, is that it doesn't use I.E. for a browser anymore, as some people mentioned above. (Which is good, cause mine was filled with viruses that I'm too lazy to get rid of.)
Edit: Doesn't work.. I think they patched it already.. Can't find the correct lines anywhere in steamui_english.txt..
Edit2: WAIT A MINUTE.. No one said those words were clickible! Yay.. No more having to click twice! Kay, new Steam is alright.
