When you are on a paper's webpage, clicking on the button extracts its information, its PDF (if available) and do a capture of the webpage and store everything structured.You can then copy citation directly from zotero, generate a bibtex file, or use libreoffice extension.All these are open source software and are available on Linux!
The only additional feature (in regard to my setup) that I can see on the homepage is the recommendation system, that can be quite interesting though. What I need is an e-ink device that lets me take notes on it and is large and fast and shows the images in color. I really wish e-ink triton was updated and deployed on a Linux (not android) tablet with a decent resolution and enough RAM to mark up PDFs, render markdown, use standard tools like git for version control and libreoffice with any other tools you wanted to install.
Even a cheaper Chinese tablet but with a decent e-ink screen would be really useful but they just don't seem to exist. I'm really happy with my i Pad for academic paper reading.
With open-source software I'm at least sure to be able to continue running the latest software version on my own, and a community can start to take over and maintain it.
Also the way data are stored in the computer can be deduced/found in the code, allowing to make exportation/importation to other software easier.
I suppose this is because researchers have really few spare free time and they don't want to use it fighting against the (linux) machines. Myself I value most the differences in hardware: I used a Samsung Galaxy Note at first for similar tasks and loved it, using Zotfile and Dropsync for keeping PDFs on the tablet.
I travel a lot, and I couldn't count on it getting through a day of mixed use.
It was a bad morning, away from base, so I went to the Apple shop at lunchtime.
I value the Linux box I use at work, and enjoy working with its tools, but easy collaboration is also important to me. This sounds similar to https:// which I dabbled with but never got into.
I'd advise an i Pad Pro 12.9" if you do a lot of reading.
The extra size means that you spend less time zooming in and out, and an app like Liquid Text ( comes into its own for bringing text and figures into the same region of the screen and reduce the amount of time you spend flipping between the two.
