Wow, good points.
Thanks, but you got me thinking!
First, I tried to use my iPad, but I found I need to jot down stuff faster then I could with the iPad. Hence the 'ol manual paper and pen.
I have space in my iPad case for paper and a few business card slots, but I'll test out how well Siri can work. I'm often in a noisy environment and Siri does well enough for me to get what I was saying, I just can't think of what to say as fast as she can write!
As for music, bring three ways to listen. For the CanJam area, bring your own DAP/Amp, if you have one for cans. For amps and DACs, bring your own DAP. For the rooms with speakers, surprisingly few of them were able to take a USB stick or SD Card. Most were able to take CDs. Most would prefer you not use your own stuff, but many had music server or Tidal, so have a song and backup song ready to recommend if you get the opportunity.
Good tips yourself! I think my iPhone or iPhone + E5 will suit for pretty much any situation, as the E5 is pretty powerful and decent DAC on its own, but it also can act as a digital transport from my phone to optical. I'll probably skip most speakers because I don't have the money in the forseeable future to upgrade past my Chane's.
I think Notes in iOS 9 has some better organization capability. That said, evernote or any of the other 100 Notes apps on the iPad will do.
