I’ve been test driving iPad Pro 12.9 as I mentioned previously, but now for a full week. Other peripherals: Logitech K380 keyboard, Logitech MX3 mouse. External display is a 15.6” 4K monitor with a quick release VESA mount and a proper portable monitor stand elevating it to proper height. This is a travel set up Only.
I have to say it’s been surprisingly good; really the main problem is the small display. With the MX3 mouse, it’s very easy to quickly switch back and forth between full-screen Citrix session on the 4K display and the iPad screen. So you can be doing your Windows stuff in Citrix, click a button, and you’re in iPad land (app switching), where you can change music, use Safari, trade stocks, chat app, etc. Whatever you want. Task switching is very fast, and there are no issues with Citrix full screen.
Issues include sound only playing through display speakers (they sound crap), although you can plug headphones into display and then it’s ok. I did not see a way to switch audio to iPad with display plugged in. With BT keyboard connected, some sound break up occasionally if you use AirPods due to interference (just turn keyboard off while in your telecon/zoom).
Also, while you can assign other commands to MX3 buttons with Assistive Touch in iPad, this screws up clicking in the Citrix window, so I leave it off (leaving back/forward and middle click buttons unused).
Yes, all of this could be done with a MacBook and then you’d have true dual display instead of just one. There is just something easy about an iPad however, making everything kind of seamless (e.g. zoom calls). Again, if my corp email did not go directly on iPad (which would not work on a Mac) through the Mail app, I’m not 100% sure I would get it.
