While the headphones are a no-brainer, I don't plan on leaving behind my iPhone and MacBook Air anytime soon.
In terms of a more holistic experience, no one does it better than Apple. Everything seamlessly syncs up from one device to another, iTunes is an incredibly useful piece of software, and AirDrop is a feature I use all too frequently. And since most of my friends also own iPhones, FaceTime and iMessage are a big part of my life.
But if I only cared about photos or constantly had to work with graphics, I'd consider switching over to the Google Pixel or Microsoft Surface Book 2, respectively. It's indisputable that the two devices excel in those ways, no matter how much of an Apple loyalist you are. And there are certainly smaller details that I'll miss, like Pixel's Night Light setting and Windows 10's Do Not Disturb Mode.
But with all that said, and despite my own gripes with Apple, I was extremely glad to have my iPhone and MacBook Air back, where the combined experience is easy, the interface is cleaner, and my beloved emojis are more aesthetically pleasing.
