Right now my tablet situation is kind of a hodgepodge, due to using old stuff. I've got a Surface Pro that's fine for PDF's, but won't run iReal Pro, so I've got an old Google Nexus tablet for that app. These things are also kind of an experiment to see if I would really benefit from either of them, or both, or neither. I'd rather find that out before spending money, rather than after.
I've learned some things from the college music students in my family. Pretty much everybody has settled on Apple -- some kind of iPad plus a third party page turning pedal. I can see why the students have switched to tablets -- the amount of material that they go through even just in the space of a week is a huge hassle if it has to be printed, often to be read just once. Printing something means finding a place on campus with a printer, in between classes / rehearsals. They need to be able to annotate PDF's, for which the Apple pen is preferred.
About the issue of what other people think: Showing up for a recital with "different" gear means that if anything goes wrong with it, you're the Goat, especially if it seems like you were trying to save money. Also, you're responsible for the reliability of your gear. And arts people are not necessarily techies. They won't grasp why you chose anything but Apple, which has been the IBM of the arts world for decades. That's not going to change.
So far my best use for the tablet: Scottish Country Dancing gigs, which are 4 hours of music, 100% sight reading, will never be played again. The BL sends me a PDF and I download it to the tablet. There are certain other kinds of gigs such as "backing up the singer from out of town" with the same situation.
For playing jazz standards, I stopped using fake books about 20 years ago and never looked back.
My main band uses printed charts, none of which have been digitized, so it's still pulling charts from the book and bringing a folder to the gig.
The organization of the PDF fake books sucks, and you have to be very quick with your fingers to look up a song without creating "dead air" on the bandstand. That's one reason why I ditched the fake books. I wrote a program that breaks up multi-page fake books into individual PDF files so that an entire library of tunes can be kept in a single folder, and searched using the file explorer. That's a lot easier than flipping through multiple books to find something.
