Real talk: I’m firmly in the Windows PC + Android smartphone camp but Apple won the tablet war.
I bought an iPad Pro (pre-M1) to run Zwift. (admittedly, I’ve switched to an AppleTV and a 32" TV for the sheer convenience of “20-seconds from cold & dark to riding in Watopia”.)
iPads even integrate well into a Windows/Android environment if you’re using it for anything other than Zwift. Best deals going are the refurbs directly from Apple.
