Word as a resume format just bothers me in general. It's easily changeable by default, leading to potential fat fingers when someone tries to print it, thus making you look bad. Layout is not guaranteed to remain the same version to version. And if you use a non standard font, it becomes a hassle on the other side to ensure it comes out looking right.

I guess these reasons haven't crossed recruiters minds.

Even worse was the apartment I am moving to. They sent me:
1 form in Excel, legal paper layout
2 forms in Word, one legal, one letter
1 form in WordPerfect, legal layout

Office and iWork on the Mac won't open Word Perfect files, and a free program botched the formatting badly. Had to take it into work and use Word 2010+Adobe PDF addon to save it back out as a PDF in the proper layout.
