I definitely would not ever be tempted to browse social media on the Boox Note 2. Although, I can say that the screen refresh is sort of slow (especially compared to a normal Android tablet), so doing any sort of web browsing other than reading long-form technical documentation is pretty annoying. Maybe the Boox tablets wouldn't be for you then. I dont want a tablet I love the no distraction and long batery life of e-reader. There are probably newer tablets from Boox that came out in the last year that might be better than the Note 2. You can of course download other PDFs apps from the Play Store. I like the PDF reader that comes with the tablet. Aside from the screen, it is mostly a normal Android tablet, so it has a web browser that mostly works (much better than the Kindle PaperWhite web browser). It is e-ink, so it is easier on the eyes. It is big, so it is easy to read PDFs of textbooks and research papers. It was quite expensive, but it had everything I was hoping for. It seemed like the best device at the time was the Boox Note 2:

I did some research on r/eink and r/ereader. I wanted a big e-ink device for reading PDFs and programming documentation. I was in a similar place about a year ago.
