This is great news. After a decade of stagnation [1], an exploit that in theory allows Linux (and Android) to be ported to iPhone, iPads, Apple Watches, and I believe, Apple TV.
There was some discussion about this on r/jailbreak, and it comes down to whether the community is willing to reverse-engineer and write drivers for the various hardware:

This is not like Desktop PCs where a game might run at less than 60fps at a certain monitor resolution, iPhone software is more like the console market, so it's like saying you have a new PS4 model with 2x the speed of last years model. You're not likely going to notice the difference except at the edges, like launching apps are slightly faster.
Apple's fan base, prior to the A6, used to be 'specs don't mstter', but once Apple got the lead in CPU speed, now specs matter. I think for most people the former is probably true.
A faster phone doesn't make your Facebook, Snapchat, iMessage, Instagram, etc experience much better and lets be honest, people are spending the majority of time in those apps.
I had three Nexus Android phones go sideways on me in their first year, over a span of 4 years.
I have had two iPhones since 2014, and only because I dropped the first one.
If I have to spend $300-$400 on replacements every couple years, I’ll go with $800 every 4-5
With Android you have a choice of the specs - bigger battery, better camera, tough build, fast charging. With the iPhone you get an average meh for not so average price.
I still have my working iPod touch from like 2011.
What did you do with those phones that they 'went sideways'? I have a number of Motorola Defy phones which are between 8 and 9 years old, they still work fine. My daughter left one of those Defy's in her pocket when she put her jeans in the washing machine, it went through a full washing cycle and still worked except for the ear piece which I replaced at a total cost of $0.50 in parts (I bought 10 for $5 including shipping, anyone need a Defy earpiece?). I only ended up buying a newer device (Xiaomi Redmi Note 5 with many of the mentioned advantages) because the Swedish electronic ID supplier stopped supporting Android 4.4. I also have an Ainol Novo Advanced 8 Android tablet from 2010, still works fine albeit with a somewhat limited battery time.
Apple makes slick devices but the slickness comes with a downside: they are among the most vulnerable devices out there, usually ending up in the bottom legion when it comes to ability to survive rough treatment [1]. Repairs end up being extremely expensive due to the enforced single supplier rule - only Apple is 'allowed' to repair the device, iOS contains checks for 'unauthorised' repairs. For the price of a single screen repair on an iPhone X ($279) I can buy a new phone for myself and for my daughter (who has a Xiaomi Redmi 4X), 'other' repairs cost $549 which is enough for new devices for the whole family. In short, Apple is the more expensive choice. If you think they're worth their price you should buy them but that does not negate the fact that you're paying more for a more fragile device with limited repair options.

This is a largely useless comparison without qualification.
