Postscript?! Until starting university, I had not encountered files in Postscript format before (I had heard of it, but not encountered). It seems to be a very common thing on UNIX platforms.

To put things in perspective. Postscript is not such on odd format. Pdf is basicially a souped-up form of postscript. Furthermore a lot of printer use postscript. A lot of programs can generate postscript, even on Win32 (for instance Word, IE). There is also a free postscript viewer (Ghostscript), this also runs on Win32.

Also, while pdf is nice (seach and hyperlinks are useful) it is also a proprietary format, the readers are free, but you have to pay money for the distiller.

Have Fun
