This is sad for me, too. I have many of my prayers on my basic Kindle (in other words, not the Fire), including those I pray after Communion (there are seven, and my memory is not what it used to be). At weekday Mass, I use my Kindle without any problems. Everyone knows what it is and why I have it. The parish secretary, however, has banned me from using it at Sunday Mass, on the grounds that people think I’m texting. Pointing out that a Kindle is not a phone did not help—I am the sacristan, and thus I’m highly visible. This puts added responsibility on me to set the example. So on Sundays I drag the missal from which these prayers were extracted to Mass with me. Book okay, Kindle not okay. This means I have to carry two missals (the one for Mass and the one with my prayers in it), which is manageable but less elegant of a solution.
OTOH, I use my phone at every Mass to record the entire homily. This drives the parish secretary bananas, but I have the permission of our pastor so she cannot stop me, no matter how much she wishes she could.

B allows me to do this because I am a foreigner and the local language is not my native tongue nor do I speak or understand it all that well. Without the ability to review the homilies at a later time in quieter circumstances, this key part of the Mass would always be a wash for me.
Father has even gone so far as to allow me to use my phone to pray the LOTH during Adoration, but I bought an actual breviary for that.
When attending Mass in my own language, I have been known to take notes. I’ve never taken any measures to conceal my paper and pen, and no one has ever spoken to me about it so I guess it’s okay!
