I have all kinds of notebook apps on my iPad. Some are brilliant handwriting emulators, while others are slick and skeuomorphic with carefully crafted UIs; some do a few things really well, and others do a bunch of things solidly enough. But I certainly didn't think I needed another one. Scrapnote has made a strong case for sticking around, though. It might look plain -- launching the app simply presents a library of staple-bound notebooks -- but its tools are powerful and versatile enough to handle most anything I threw at it.
