Turns out Anand, that PDF Rider really is too cut down to be useful.
From another thread, I went for PDF Exchange Editor Free and I believe it just takes all the cakes home.
I just did a multi page cut from a document, something like pages 1-3,18-20 + save as one document!
Now I'm investigating if their demo Pro advanced features are worth about $43 to upgrade.
But even in Free, they're the ones to beat and darn close to what the other guy was looking for. I consider the best of Freemium to be when the free version is *really solid*, and lets you just get work done, and then Pro has some one or more absolutely stunning features. PDF Exchange looks really close to that model because as I remarked in a couple of threads, notice for ex PDF Rider has no viewer, so you can't see what you're chopping, and it can't do anything near as fancy as the multi page edit I just did.
And if there IS a killer app feature, $43 is way better than Adobe's multi hundred price tag!!
