I agree with the both of you! I prefer reading on my iPad, but I was often annoyed at how annotations were either stuck on the thing, or harder to make. GoodReader (iOS) is decent for making and syncing pdf annotations. It's still not as easy as a laptop, but sometimes the benefit of reading on an iPad is worth it for me. For epub files, however , I almost always exclusively use my iPad. There's an app called Marvin that allows you to instantly select (or select + highlight) a sentence, and grow the selection with one tap. I find that almost more convenient than my laptop. It also syncs with Calibre, although that can take a bit of work to set up properly.
