I recently discovered the superiority of the free Preview.app on Macintosh systems over the free Adobe Reader.
A lot has been said elsewhere why that should be the case, e.g. here and here. I am going to keep this short and highlight two key features that stand out for me personally, that might or might hot have been covered elsewhere.
Enter Preview.app – a simple Cmd-D and voilà, the page in that PDF is bookmarked. Then you can close that particular PDF, open another one, and the bookmark will stay there. So the bookmark will stay with you as long as Preview is still open. Then if you want to bring it back, all you have to do is select that bookmark from the Preview menu, and lo and behold, it will open that other PDF at the page where you bookmarked it.
How neat is that? I wish I discovered this functionality ages ago.
In addition Preview supports retina displays, unlike the Adobe Reader. You can underline text in Preview, not just highlight. It’s an all around winner. And it’s so much more lightweight in comparison too.
Kudos to Preview and the team behind it for changing my reading experience for the better.
