Mac OSX style font smoothing. I’m sold. I don’t know how they’ve done it, but they have – it looks and feels exactly like the Mac version. For the longest time, I’ve loathed Windows’ subpixel rendering, even Gnome/KDE put ClearType to shame. I’m just pissed that now the rest of Windows looks even more drab than usual.
Don’t get me wrong, I like Firefox – but unless you’re bleeding edge, it’s not W3C compliant, and the Gecko rendering engine is getting a bit long in the tooth. All that being said, I don’t recommend Safari if you’ve got less than 1GB of RAM.
