[ExI] Writing: Scrivener - Mac or PC?

[natasha at natasha.cc]

Hi -   I was just looking at Scrivener and it is mighty nice to look  
at.  But when I went to purchase it, it did not look so hot for the PC:

Mac:  http://www.literatureandlatte.com/scrivener.php
PC:   http://www.literatureandlatte.com/scrivenerforwindows/

Is this because more designers use Macs and marketing hooks them with   
a pretty webpage?  It certainly made me want to get a Mac and toss my  
PC.

Has anyone used Scrivener?  What do you think about it?

Thanks!

Natasha
