The Laptop Upgrade I Didn’t Make

Taiwan summers can be hot and humid—the kind of weather that makes it very tempting to step outside, relax, and enjoy an Italian spritz instead of sitting down to write a blog post. That said, it is encouraging to know that at least one beloved reader follows this blog closely and has been kindly reminding me to keep writing. So here I am.

Recently, I had a surprisingly thoughtful conversation with my most-used AI chatbots. I tend to use several of them interchangeably, partly because I enjoy experiencing their strengths and weaknesses firsthand. In a way, this has become my own informal benchmarking exercise.

The topic was simple: should I upgrade my laptop?

I am both a Mac and Windows user. After more than 20 years of working across different computing environments, many shortcuts and hotkeys are deeply embedded in my muscle memory. I can move very quickly on a Windows laptop, especially with the ThinkPad TrackPoint—the little red dot that many ThinkPad users either love or never quite understand. With a new generation of lightweight laptops coming out, and with travel ahead, I started wondering whether it was time to upgrade.

On paper, the Windows options were very attractive. They often offer better specifications, especially around display quality, ports, connectivity, and keyboard experience. For someone who still values a great keyboard and flexible I/O, those are not small details. However, the trade-offs remain familiar: battery life and raw performance are not always at the same level.

As a former CPU design manager, I fully appreciate what Apple has achieved with its silicon. Apple’s laptops deliver an impressive balance of performance and battery life. That kind of system-level engineering excellence is not accidental. It reflects deep integration across silicon, hardware, software, and power management.

At the same time, excellent engineering does not automatically cover every user need or innovation gap. I was reminded of this when I switched from an iPhone to a foldable Android phone after many years as an iPhone user. The Android experience may not always match the iPhone in battery life or overall polish, but the foldable form factor is much closer to how I actually use my phone today. Sometimes the best product is not the one that wins every benchmark. It is the one that fits your workflow.

What made the chatbot conversation interesting was not only the factual comparison between laptops. I was impressed that the AI remembered my background, my current role, my previous experience, and even how I use my machines. Technically, what amazed me was not the laptop discussion itself, but the underlying AI capability. The models were able to retain context, retrieve relevant details, and apply them in a way that felt genuinely useful.

In some sense, this reminded me of old computer architecture discussions around caching, speculative execution, and memory hierarchy. The core question is similar: how do you keep the most relevant information available at the right time, while avoiding unnecessary overhead? Today’s LLM systems are solving a very different problem, but the intuition feels familiar. Good performance is not just about raw compute. It is also about knowing what to remember, what to retrieve, and when to use it.

Eventually, the AI gave me a detailed assessment that I mostly agreed with. My attraction to a new Windows laptop was real, but much of the inconvenience I felt with my current setup came from muscle memory rather than actual limitations. The MacBook Air may not be the lightest laptop on the market, but its combination of battery life, performance, portability, and reliability remains outstanding.

So, at least for now, I am keeping my MacBook Air M4.

Instead of spending money on something that may only satisfy a temporary itch, I will let this laptop continue doing its job. And perhaps I will save the upgrade budget for something more meaningful—or at least for a few more Italian spritzes during the Taiwan summer.And occasionally, taking the wrong exam helps you get to the right place.
