1.2kg Wings: Why I Switched from MacBook Pro to M4 Air

After three months of dedicated blogging, I finally earned my first income: 180 yen.

While it may seem like a small amount, to me, it represents a significant milestone—my official entry into the world of professional writing. It is the first tangible step toward funding my expedition to Mount Everest. Therefore, instead of viewing this as mere pocket money, I decided to immediately reinvest it in my primary tool: the new M4 MacBook Air.

This was not just a simple hardware upgrade; it was a revolution for my creative flow.

Goodbye, Heavy Anchor. Hello, Desktop Freedom.

My previous MacBook Pro, while powerful, had essentially become a desktop computer. Its weight required significant mental preparation just to take it out of the house. As a result, I was confined to my desk at home, completely neutralizing the primary benefit of a laptop: mobility.

The M4 MacBook Air is entirely different. At just 1.24kg, it feels nearly weightless compared to my previous setup. The design philosophy immediately communicates that it is built to be carried.

Right now, I am writing this post while sitting deep on my sofa, with the MacBook resting comfortably on my knees. This level of freedom and relaxation while working was something I could only dream of during my MacBook Pro days.

Silent Power and Zero Mental Friction

The most shocking aspect has been its absolute silence. It generates no heat whatsoever, and even during heavy tasks, there is no fan noise because there is no fan. This silence creates a “magic” that makes carrying it around feel completely natural.

In the past, I experimented with using an iPad Pro combined with a Bluetooth keyboard. However, I always felt a sense of awkwardness—both from carrying multiple devices with overlapping roles and from trying to force a tablet to do a PC’s job.

The moment I opened the MacBook Air, that hesitation vanished. With its larger screen and integrated, tactile keyboard, there is zero stress hindering my thoughts. Facing this overwhelming sense of capability, I realized that I had not truly owned a “personal computer” in the truest sense of the term until now.

A Complete Tool Needing No Accessories

Another wonderful aspect of the MacBook Air is that it requires no “extras.”

During my iPad era, I found my attention constantly diverted by new accessories—covers, pencils, screen films. It felt endless, and as a gadget lover, I was always distracted by the desire for “one more thing.”

The MacBook Air requires none of that mental clutter. Thanks to its incredible battery life, I don’t even need to carry a heavy charger if I charge it at home (in fact, today, after a full day of use, the battery has barely budged from 88%). The moment you open it, the device is ready to deliver 100% full power on its own. This minimalism is the hallmark of a professional tool.

Vital Gear That Remains and Strategic Investment

I did not replace everything. I still rely on two “god-tier” tools that are perfectly suited to my environment.

The first is my MOFT stand, which adds a perfect typing angle. I intentionally chose the non-adhesive version, allowing me to seamlessly switch it between my work laptop and this MacBook Air. It is my ultimate partner, ensuring I can reproduce “my” perfect typing ergonomics anywhere.

The second is my USB hub. I actually ordered a new one to go with the Air, but upon closer inspection of my existing SD card reader, I realized it already had an HDMI port. It worked perfectly with the Air. I immediately cancelled the order for the new hub, preventing unnecessary expenditure and keeping my setup lightweight.

By combining the money saved from the hub with the money I saved by not eating out today, I bought a full week’s supply of meat. I will eat plenty of protein and go to the gym to train my core and back. This is essential for building the physical frame needed to carry a heavy backpack toward Everest.

Strategic investment in my tools (the Mac) and strategic investment in my body (muscle). This contrast defines my strategy as I aim for Everest in my 40s.

Conclusion: I Have Reclaimed the True “PC”

My roles are now clearly defined. My smartphone is for communication and consuming content. The MacBook Air handles everything related to “creation,” including my blog and future projects.

Today, I took the Air to the gym as a matter of course. There was absolutely zero resistance to carrying it. Working with a sharp mind immediately after exercise felt effortless.

The knowledge that this stress-free experience will continue brings a deep sense of relief. Having gained these 1.2kg wings, I am certain that my journey towards Mount Everest will accelerate rapidly.
