But all of these ELNs are targeting replacing wet lab notebooks. I tried many ELNs and even wrote one, but I don't think there is any replacing paper notebooks for wet lab research. Even when you have some computational aspect, you can print out a figure or table and attach it to a page in the notebook. (Now reproducible dry lab notebooks are a whole other matter)
