The odd thing is that right now, I feel kinda indifferent between upgrading to the 17 pro max, and keeping my 13 pro max. I admit that it's been a very busy and hectic past few months (busy with juggling various duties in school), and I don't know if that is what's cutting into my enthusiasm for new tech products, or just the fact that my current apple devices still work great.
My purchase history so far:
2020 - M1 MBA (base model), still going strong. I have put off the decision to get the 15" M4 MBA a few times already.
2021 - 13 Pro Max. Does what I need it to do, and battery life has been great overall. Except yesterday. iOS 26 made my phone's battery drop pretty quickly. Not sure what's up with that.
2022 - Apple TV and AirPods Pro 2.
2023 - Nothing, I guess?
2024 - M4 iPad Pro (direct upgrade for my 2018 iPad Pro), plus Apple Pencil and Magic Keyboard. Don't regret this, because I use my iPad daily for work. Also S10 Apple Watch to replace my S5 (and you may have heard about my issues with the colour peeling). I have taken out my S5 watch to wear a couple of occasions and aside from the improved battery life, I don't really feel any difference.
2025 - Nothing yet so far.

I actually just returned my APP3 yesterday, after trying it out for a week. Just didn't feel as comfortable as my APP2. And the 17 pro max is out of stock everywhere.
It feels like my apple devices are on a replacement cycle - I will get a new one when the current model breaks down or is no longer supported. I have played with the new iPhones in the Apple Store, they are nice devices, and I am fine with just sticking with my current hardware for now at least.
