Special temporary top-of-page insert for eInk (images upgraded to Retina resolution via Samsung Galaxy Tab S2 screensnaps):
This is a new Page so I can use it whenever I’m in a store and need to do the test.
If you have a tablet or phone and want to do it, go ahead. A video on YouTube I could embed in a post would be great too. With everyone having a video-capable cellphone these days, I’m surprised I’m the only one doing these.

Update: When I tested the below APK Downloader links in the field, I was presented with a Session Timeout message. Just click the green button to re-generate the download link. Also, sometimes the download link wouldn’t work depending on how screwed-up a tablet was that had the Google Play Store on it. Maybe I should eventually just put these in my Google Drive, but that’d yield obsolete versions too quickly.

Mike,
I know you don’t like Windows OS, but you should really take a look at this video at around 17:50, where he shows PDF performance on the Lenovo Thinkpad 8 tablet. I’m not a fan of the port placement on this tablet, but it is a very nice tablet. This is now on my watch list with MiPad, iFive’s MX2, and the Ramos i9s.

That SciAm PDF has no real relation to GBooks PDFs. They are made entirely differently.
That may be true, but I still think a Windows device will handle PDF documents better. :)
Mike,
Have you consider using XODO DOCS?
So far, I’m satisfied with the quality and speed when using this app.
I think, this could be one of the best pdf reader in Android.
I’ve never heard of it. Is it free — or at least have a demo mode that will allow me to open a PDF at a Best Buy?
It’s free.
As I found out. I tried it. It was bad on the Tab A 8.0. Post coming.
