680 Euros quoted from the apple store in berlin for a 2012 macbook.

Everything apple is vastly more expensive in europe, can't be compared to US contexts. You pay a few hundred more at least for iphones too. Seriously, a good population of people actually fly to Portland to stock up on apple gear, and fly back to Europe or India or other places. No sales taxes in Oregon too so you save even more, sometimes its enough to pay for airfare compared to buying in California even with 10% s…

I don't think it would turn out a plus if I fly over to get it serviced.

Assuming you want to do repair, I have no interest in repairing anything. In fact I'll happily part with my money to not have to deal with repairing stuff. Same applies to my car.

Do you have a threshold for this? I assume that if your laptop wasn't working and all you had to do was take a single screw out then you'd do it, rather than taking it to a repair shop or buy another. Or if the repair cost was extreme, but it was relatively easy to fix it yourself. Your point of view is valid of course. At the same time I believe many people don't have sufficient money to allow them the luxury of nev…

> Do you have a threshold for this?

Not OP but I have a really high threshold for this. I don't want to own a house and rent because of this.

The problem is knowing what's actually broken in the first place. A friend of mine took their laptop to Geeksquad and they told my friend the power circuit was broken and the motherboard needs replacing. I checked the charger and realized the charger was broken and told them to buy a new one and what do you know it works fine. Most people are generally incapable of figuring out what actually is broken and will go to a repair place anyway. Or if the device is old enough they will just buy a new one. These days devices last a long time if you take care of them physically so by the time something starts failing it's likely already time for an upgrade for most people.

So the actual DIY repairability of laptops just doesn't matter for the vast majority of people. What Framework is doing is awesome amazing though and I hope it does encourage companies to make easier to repair computers to lower the actual cost of repairs.

Silly idea in tech, the hardware will be long outdated before someone look for parts which are going to be overpriced, and the company might be gone forever. You can buy common business laptops such as thinkpad and swap the parts easily and cheaply. People aren’t swapping their 2011 i3 for a 2011 i7 if they care about performance; they’re getting an i5 from 2018. None of these swappable parts are unique aside from th…

I disagree. My thinkpad x230t is still going strong nearly 10 years later (extreme example). With 16GB of ram and an SSD it's still a decently capable machine. If you're the type of person that needs the _fastest_ computer then yeah obviously you're upgrading every year. Or if you work on large codebases, etc. But if you don't care about that, you can easily go 4+ years with your laptop. Yes computers have gotten fas…

On the other hand, my x200t, which isn't that much older, is minimally functional for the web and is effectively nonfunctional for YouTube.

I keep it around because it works as a kiosk in my recording studio, but that's about it.

>whatever failure damaged the SSD is statistically likely to compromise the reliability of the rest of the board Sorry, but how? That's just reads like BS. SSDs have limited lifespans due to the limited write cycles of the NAND chips. So no, what damages NAND does not damage the rest of the board. The more you write and swap to flash, the faster it wears out, taking your Macbook down with it when it dies. Granted, I…

Limited write cycles will produce data corruption, but what the article explains is that Apple is using the Flash in M1 macs in a similar way to other ARM devices, that is, they have the firmware there. I don’t know how much time do you expect your mac to last, but write cycles on your firmware should not be much of a concern.

Right, but I get the impression that the firmware vies for space with the rest of / et al.

Sooo that means the wear leveling had better be ahead of whatever lifetime writes you throw at the system, or...

And the used 2011 i3, that wouldn't become garbage if it were repairable would get sold to someone less performance / price consciousness? Now it gets trashed.

Nope, nobody wants it. You can try to sell it though. People don’t want even a free processor that needs an expensive mobo they’ll need to buy our own when they can get a much better ryzen board and a cheap processor that will trounce it. Nobody wants these old processors, many are so useless they’re being drilled for keychains.

While I certainly can't speak for everyone - I've had a 2011 Dell Inspiron that I upgraded from the i5-2450m to an i7-2670qm a couple years ago. Additionally the RAM and HDD were upgraded/swapped for SSDs.

The computer now lives with my mom, who needs a simple but reliable device. The i5 was sold on ebay for a few bucks to some lad or lasse who may have needed it for a cheap laptop build. Decade old computers aren't vastly different from today in terms of day to day use. Capabilities and high performance is one thing, but using devices longer, and upgrading entire systems less frequently is both better for your wallet, and better for the environment.

I don't want to repair my laptop either but I want to upgrade my laptop a year or two down the line. The modern laptop can go much further with a simple upgrade like RAM or SSD HD. Apple's laptop is really limited in this way. The older generation of Apple's laptop allowed you to upgrade RAM and HD.

Apple is targeting the population that has no need for upgrades.

Watching videos, browsing internet, sharing pictures and videos, video calling and basic spreadsheet/word processing needs no upgrades.

I use a 2015 MacBook Air and I don’t need an upgrade, and I probably do more on my laptop than 80% of people.

In practice, exhausting NAND write endurance is usually not what causes SSDs to fail in the field. It is especially unlikely to be the underlying cause of unexpected and seemingly premature catastrophic SSD failure. Also, it is not possible for an SSD to decrease your usable storage space over time. That would break any partition table format or filesystem that expects an ordinary block device. It also wouldn't win y…

>> It also wouldn't win you any significant increase unusable lifespan, because when your drive starts retiring large numbers of blocks, all of your blocks are on the verge of failure.

That's not true. Blocks degrade when written to. Most files are written once and read many times.

This is a tangential question. I adore my Thinkpad x230t but it has a whopping ~1 hour battery life at this point. Do you leave yours permanently plugged in or do you have some sort of modern battery solution for our ancient beast with an amazing keyboard?

You can hack the bios to remove the DRM and use 2012 aftermarket batteries, or replace the cells. I dumped my x230, not worth the horribly priced aftermarket (if you break your screen it’s almost as expensive as another laptop and you’ll need to repair it). I love my newer x250 with no DRM for WiFi, 2x SSD slots, cheap batteries that can hotswap, cheaper 1080p IPS replacement screens, and 11hr+ battery life. The x230 already lost the classic keyboard, the new one is fine, and the speakers are retardedly still on the bottom but it’s much louder.

I ended up just buying a new battery for my t540p. I was reluctant to because I didn't think it could possibly last much longer with the abuse it's been subjected to, but, it's still going strong a year later.

They’re so much cheaper than the 2013 ones. I love the new battery platform.
