Behind in specs? Depends on which specs I guess — but CPU/GPU performance is AFAIK pretty great? https://www.tomsguide.com/features/iphone-15-pro-benchmarks
Features, yeah, depends on what you’re looking for. AFAIK iPhones are the only mainstream phone to offer satellite texting though.
I have both an iPhone (work) and an android (personal), and they both…kinda just work 🤷
Back in the day I was running GLTron on an Athlon 1800+ w/Nvidia GeForce FX 5200 (I think?) and I was running dual monitors. GLTron didn’t like using both screens since it presented as a peculiar resolution. So I emailed the GLTron dude and he quickly emailed me a patch that let me run the game across both monitors (bezels not an issue because I was doing multiplayer split screen).
What a great game.
