On people coming up to request things in the middle of a song. I don't think they are being rude on purpose, but most have the combination of alcohol and what they see on TV and movies, especially when there is a single piano player. I forgive the alcohol because the more they drink, the better we sound

Back on topic........
Leilani uses a music stand. Not the old Manhassets we used in school, but one with a locking clutch to keep the heavier than a piece of music laptop from lowering the tray.
Here we are playing at the birthplace of the Navy SEALS (all the stuff on the wall was left by SEALS during their annual muster). One music stand is for her laptop, and another for her Buchla Thunder Tactile MIDI controller.
I've got mine on my keyboard "A frame" with a small monitor in the middle. I actually only need one, but eventually I'll need the second one, so it is always up and ready. Since 2002, I've had to go to the spare twice, but both times they saved the show.
I use one (stage left) for the music, and the other (stage right) to run the backing tracks that I create myself. I could do both on the same computer, and redundant data we have is on all 3 computers so we are in good shape if any one of them fail. (we also have back-up data on flash drives)
Important: Put some Velcro on the stand and the laptop. It makes it difficult to knock off -- especially when one of those people with enough alcohol in their system to make you sound great come up and lean against the equipment because their head is swimming
