It's not a classic thinkpad, but my thinkpad from 7 years ago is still going strong.

Recently I decided to do a service on it for the first time, and I was absolutely stunned by how little dust had built up in the CPU fan and the interior in general, after 7 years of usage, often sitting on top of a couch or bed, near my long-haired Norwegian forest cat Rufus. All it needed was a litle puff of computer duster and it was good as new. That's very good design of the air intakes and is a huge factor in the machine's longevity.

I did computer repair professionally for a while, and one of the most common causes of irreparable death I saw in laptops was massive dust buildup in cpu fans and consequent heat damage to surrounding components. I'd sometimes see this in 2-3 year old laptops even.

Funny to think that something as simple as the shape of an air intake opening can have such a profound impact on the lifetime of a device.

The other thing that Thinkpads are unrivaled at is protection for the display. People like to say macbooks are sturdy, but they are quite prone to cracked displays because of Apple's obsession with smaller bezels. The thinkpad ofc has t34 style angled armor for its display. Can't remember ever seeing a Thinkpad with a cracked display. And I carry my Thinkpad around in just a backpack with no sleeve, often the Thinkpad is the only thing in there, and it regularly impacts the floor when the(thin-bottomed) backpack is put down while sitting down on the bus or getting home.

I wish that Framework could attain the same lofty levels of "second hand market success" that ThinkPads enjoy. A lot of the "Thinkpad fans" I've talked to genuinely want them, or respect them for similar reasons they enjoy the ThinkPad legacy.

ThinkPads are durable but every day they get older, slower and more difficult to source parts for as collectors entrench themselves and the requirements of operating systems (and the "modern web") worsen

Framework laptops are wonderful, modern and (arguably?) cheaper to own in the long-term thanks to being able to replace components, particularly the entire mainboard as time progresses.

*But* they're a tiny boutique manufacturer. Their barrier to entry is that of a pretty hefty modern laptop, versus buying a T420 for practically pennies and performing all kinds of aftermarket "mods" to it. 51nb's "FrankenPads" especially breathe incredible new life into old IBM and Lenovo stock.

Combine this with the fact that being the "defacto business laptop" for nearly three decades (along with perhaps Dell) means there's enough Thinkpads on Earth to probably stretch end-to-end around the moon and back

Personally I think beyond T450 generation, i.e. over 10 years old systems, you are starting to make pretty severe compromises. T440 generation had really bad Trackpoint setup, and older hardware starts to lose features. Random stuff that T450 has that T400 doesn't

* USB3

* Up to 32 GB of RAM (vs max 8 GB for T400)

* M.2 slot (for SSD), 6 Gb/s SATA (vs 1.5 Gb/s on T400)

* x86-64-v3 (AVX2 etc) and OpenGL 4.6

* Dual-band AC wifi and BT4.0 (optional 4G LTE WWAN)

* DisplayPort with 4k@60Hz output

* Slightly larger screen estate (1600x900 vs 1440x900), with FHD 1080p display option

* Dramatically better battery life

* Backlit keyboard

Many of these are not merely nice to have but also ensure longevity by being compatible with lot of other modern stuff. On the other hand I do believe that T450 generation device might remain viable daily driver for a long while still. From the specs the biggest obvious shortcoming to me is the lack of USB-C, especially USB-C charging. But besides that, it seems pretty usable system.

For reference, I have old X240 that I still occasionally use.

The tightness of hardware integration isn't a bug, it's genuinely a feature; In fact, it's the defining feature that makes Apple hardware great. Socketed RAM, CPU, and Storage just weren't worth the tradeoffs, namely size, weight, cost, and performance. Including those modular interfaces just wasn't worth it when the internal interfaces would be obsolete within 5 years, and the average user was replacing sub-components 0 times over the life of the device.

The user being able to swap parts easily is _neat_ but it's just not an required feature, any more than the user of a car being able to easily hot-swap the engine. The right level of integration provides a tradeoff the maximizes reliability, cost, performance, and repair. A professional can still replace almost any component of a modern laptop, with a few thousand $ of specialized tools, and the battery, the only component with a fixed lifetime, can be easily replaced at home.

I really hope Framework can continue to develop hardware with documented repairability, without falling for the myth that tight integration and quality are mutually exclusive.

> A [macbook] battery replacement involves carefully prying out a glued component.

Can't speak to every model, but it's not always like this. I just swapped the battery on my 2020 M1 Macbook Air, and it's much easier now. The battery is glued to a metal tray that unscrews and lifts out of the laptop. It is discarded with the old battery. The tray is also held down with pull-tab adhesive strips, but they are trivial to remove - similar to what "command hooks" have.

I've also done a battery swap on a 2015 Macbook Pro 15" - much harder. Each individual battery cell is glued directly to the chassis, and removing each one involves a lot of prying and praying it doesn't puncture or decide to detonate.

Back to the macbook air, I've also replaced the screen and USB-C ports. It's not that bad.
