I also think the new mechaism (after second generation) is highly inspired by all the buttons you’d found in iDevices, check out how much similarities between the keys and a volume control. Most cherry keyboard are prone to liquid damage, and that didn’t stop the one who loves it. No doubt the lifespan will be much longer than rubber dome, I’m just saying that simpler design are less prone to failure, even though I fully support the new key design. It’s kinda surprising that you can fix most the problem by simply adding a layer of silicon. A hard key with a soft fixed base would probably be ok to type on and easily replaced. Old mobile devices used rubber keys and were very comfortable to type on due to the softness of the rubber. They could reduce the key travel even more, the comfort is more about sponginess of the press. They could update the design in future with more easily removable keys and if they can get rid of the switch and put a mechanism in the hinge, that could increase the travel by removing some of the base plate or they could make the keys like the trackpad with small feedback units so you can do a harder press on a key and it can insert accented characters or capitals or the alt-character for the number keys and they can put any kind of cushioning under the key. If older models are brought in for repair, they could easily switch them out for the updated ones with the membrane. No mechanical parts will be completely impervious to failure but this looks like it will do a pretty good job of improving the reliability and the key cushioning is a benefit too. Here, they blow sand over the updated keyboard and the sand grains are blocked from getting in: iFixit tested the old one before and here the key got jammed with a grain of sand in the lower right corner: Apple will have the failure data and make corrections to minimize them. They couldn't keep using the rubber dome if they wanted to have a thinner profile, more stable keys and uniform backlighting and if both designs serve the useful life of a computer of about 8 years then they do the job just fine. But that doesn’t mean it will not work most of the time, though (In fact, it’s not that complex compared to many other “mechanical” switches). That being said, i think it will definitely not as rugged as the rubber dome, because simpler parts have less failure, even if the third-generation fixed all the “dust” issues. The patent describes the exact protectant film we see in the new keyboards and is described as to "prevent and/or alleviate contaminant ingress." Indeed, in comments to certain media outlets, Apple said the revamped keys are not intended to improve reliability.ĭigging deeper, a patent issued to Apple seems to confirm that theory. The immediate assumption, was that no, the newly designed keys did not nullify key failures. Though it says problems are relegated to a small percentage of MacBook owners, Apple last month initiated a service program for those with affected machines. When Apple launched the latest MacBook Pros earlier this week, there was a lot of debate as to whether the updated, third-generation butterfly keyboard had fixed the criticized failure problem that has spawned multiple lawsuits against the tech giant. While not confirmed by Apple, iFixit theorizes that the new keyboard's newfound quietness is merely a side effect of the membranes real purpose, to keep debris out of the keys. This thin film, located under each individual keycap, appears designed to prevent dust and debris from interfering with key operation, an issue that cropped up in previous generation butterfly keyboards last year. Repair specialist iFixit tore down the latest MacBook Pro and quickly found a noticeable change to the keyboard design - a thin, silicone membrane surrounding each butterfly mechanism.
