I prefer PDF files rather than ebook formats. I don't like the idea of being locked into a particular technology, be it Apple's or Amazon's.
I consider PDF viewers to be superior to the experience offered by ebook viewers. For example, Having to tap the left and right side of the screen to move between pages is a pain compared to swiping up or down in a fluid motion.
Another issue is the waste of space by trying to simulate paper. On my iPad both Apple's and Amazon's ebook readers display almost an inch of white space margin all around the page. On the same device PDF viewer will zoom text to use the entire screen with a double tap of a paragraph.
And then there's zooming.
PDF's are easier to view on multilple devices. I keep all my books on Dropbox. They are instantly available no matter where I might be.
