I am, but not for myself as I prefer to use Android (currently on OnePlus 10 Pro 256GB) - I will definitely be buying a 14 Pro along with a Series 8 Watch for my mother, who lives alone and can sometimes have health issues that the watch can help out with. I really admire Apple for the amount of work and time they've put into focusing on health, safety and privacy.
Eventually plan to migrate back to iPhone myself, but I'm holding off until Apple implements fast-charging and hopefully USB-C (at around the same time). For my usage, the OnePlus having a fast-charging 5000mAh battery is just too good to give up just yet. I got a deal on this phone at $500 so I am fine with waiting to see what iPhone 15 brings.
