Some devices only allow up to a certain number of simultaneous Bluetooth connections (we’ve heard of a 3 limit max on certain devices), but just a power meter and smart trainer will be fine.
While we don’t publicly share benchmarks, the fan-run site, Zwiftalizer, does have some data it’s collected and you can get an idea of what performance you’d see on an iPad Pro.
I have a gaming PC and laptop that both run Zwift well but don’t use them at all any more. I’m only Zwifting on an iPad Pro(9.7 and now 10.5) with a Tacx Neo.
IPads are easy to pop into a stand in front of me, within arms reach, and love being able to touch the screen to control everything. Easy to tap a riders name and give them a Ride On etc. I also love that I can have Netflix running on the corner(picture in picture) of the iPad screen while I’m Zwifting. It really makes the time fly by.
I vote for the IPad as long as it can do all the other computing tasks that you need your iPad or MacBook to do…
