The original Evince was and still is my favourite PDF reader too. Unfortunately the newer versions feature a Gnome 3-style UI that renders the program unusable for me.
Indeed. I've found xpdf is OK for quickly viewing most PDFs, but Evince is the only one I've found that has decent support for form-fill-in.
Also on windows.
Yeah. Well most Linux software is kind of multiplatform anyway, or at least portable. My reason for citing Linux here more than Windows is that Evince was included by default in many distros.
